This will make sure that audio callbacks do not race with
component bind/unbind.

The port_mst_index parameter was reserved for future use, but
maintainers prefer to add it later when it is actually used.

When the audio codec is enabled or disabled, notify the audio driver.
This will enable the audio driver to get the notification at all times
(even when audio is in different powersave states).

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.3
Not many updates to the core here, but an awful lot of driver updates
this time round:
- Factoring out of AC'97 reset code into the core
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers.
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650.
- Initial driver support for Intel Skylake devices.
- A large number of cleanups for Lars-Peter Clausen and Axel Lin.

Separate the functionality using sequences of register writes from the
functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.
This also updates all the clients of multi_reg_write/register_patch.

The routines in scsi_rpm.c assume that if a runtime-PM callback is
invoked for a SCSI device, it can only mean that the device's driver
has asked the block layer to handle the runtime power management (by
calling blk_pm_runtime_init(), which among other things sets q->dev).
However, this assumption turns out to be wrong for things like the ses
driver. Normally ses devices are not allowed to do runtime PM, but
userspace can override this setting. If this happens, the kernel gets
a NULL pointer dereference when blk_post_runtime_resume() tries to use
the uninitialized q->dev pointer.
This patch fixes the problem by calling the block layer's runtime-PM
routines only if the device's driver really does have a runtime-PM
callback routine. Since ses doesn't define any such callbacks, the
crash won't occur.
This fixes Bugzilla #101371.

fnic_queuecommand() to avoid deadloack
We added changes in fnic driver patch 1.6.0.16 to acquire
io_req_lock in fnic_queuecommand() before issuing I/O so that io completion
is serialized. But when releasing the lock we check for the I/O flag and
this could be modified if IO abort occurs before I/O completion. In this case
we wont release the lock and causes deadlock in some scenerios. Using the
local variable to check the IO lock status will resolve the problem.

The TI crossbar irqchip doesn't provides any facility to configure the
wakeup sources, but the conversion to hierarchical irqdomains set the
irq_set_wake callback to irq_chip_set_wake_parent. The parent chip
(OMAP wakeupgen) has no irq_set_wake function either so the call will
fail with -ENOSYS. As a result the irq_set_wake() call in the resume
path will trigger an 'Unbalanced wake disable' warning.
Before the conversion the GIC irqchip was the top level irqchip and
correctly flagged with IRQCHIP_SKIP_SET_WAKE.
Restore the correct behaviour by removing the irq_set_type callback
from the crossbar irqchip and set the IRQCHIP_SKIP_SET_WAKE flag which
lets the irq_set_irq_wake() call from the driver succeed.

The ARM GIC requires that all interrupts which are not used as a
wakeup source have to be masked during suspend.
The conversion of the crossbar irqchip to hierarchical irq domains
failed to mark the crossbar irqchip with the IRQCHIP_MASK_ON_SUSPEND
flag and therefor broke the suspend requirement of the GIC.
Before the conversion the flags were visible because the GIC was the
top level irqchip. After the conversion the crossbar irqchip is the
top level irq chip whose flags are evaluated in suspend_device_irq().
As the flag is not set the masking of the non-wakeup irqs is not
invoked which breaks suspend.
Add the IRQCHIP_MASK_ON_SUSPEND flag to the crossbar irqchip, so the
GIC interrupts get masked properly.

The conversion of the crossbar irqchip to hierarchical irq domains
failed to provide a mechanism to properly set the trigger type of an
interrupt.
The crossbar irq chip itself has no mechanism and therefor no
irq_set_type() callback. The code before the conversion relayed the
trigger configuration directly to the underlying GIC.
Restore the correct behaviour by setting the crossbar irq_set_type
callback to irq_chip_set_type_parent(). This propagates the
set_trigger() call to the underlying GIC irqchip.

Commit c48a11c7ad26 ("netvm: propagate page->pfmemalloc to skb") added
checks for page->pfmemalloc to __skb_fill_page_desc():
if (page->pfmemalloc && !page->mapping)
skb->pfmemalloc = true;
It assumes page->mapping == NULL implies that page->pfmemalloc can be
trusted. However, __delete_from_page_cache() can set set page->mapping
to NULL and leave page->index value alone. Due to being in union, a
non-zero page->index will be interpreted as true page->pfmemalloc.
So the assumption is invalid if the networking code can see such a page.
And it seems it can. We have encountered this with a NFS over loopback
setup when such a page is attached to a new skbuf. There is no copying
going on in this case so the page confuses __skb_fill_page_desc which
interprets the index as pfmemalloc flag and the network stack drops
packets that have been allocated using the reserves unless they are to
be queued on sockets handling the swapping which is the case here and
that leads to hangs when the nfs client waits for a response from the
server which has been dropped and thus never arrive.
The struct page is already heavily packed so rather than finding another
hole to put it in, let's do a trick instead. We can reuse the index
again but define it to an impossible value (-1UL). This is the page
index so it should never see the value that large. Replace all direct
users of page->pfmemalloc by page_is_pfmemalloc which will hide this
nastiness from unspoiled eyes.
The information will get lost if somebody wants to use page->index
obviously but that was the case before and the original code expected
that the information should be persisted somewhere else if that is
really needed (e.g. what SLAB and SLUB do).

Meelis and Helge reported that 3a9ad0b4fdcd ("PCI: Add pci_bus_addr_t")
caused HPMCs on A500 and hangs on rp5470.
PA-RISC does not set ARCH_DMA_ADDR_T_64BIT, even for 64-bit kernels, so
prior to 3a9ad0b4fdcd, we always used 32-bit PCI addresses. After
3a9ad0b4fdcd, we do use 64-bit PCI addresses in 64-bit kernels, and
apparently there's some PA-RISC problem related to them.

We should not assume any particular hardware topology. Commit d0751b98dfa3
("PCI: Add dev->has_secondary_link to track downstream PCIe links") relied
on the assumption that every PCIe hierarchy is rooted at a Root Port. But
we can't rely on any assumption about what hardware we will find; we just
have to deal with the world as it is.
On some platforms, PCIe devices (endpoints, switch upstream ports, etc.)
appear directly on the root bus, and there is no Root Port in the PCI bus
hierarchy. For example, Meelis observed these top-level devices on a
Sparc V245:
0000:02:00.0 PCI bridge to [bus 03-0d] Switch Upstream Port
0001:02:00.0 PCI bridge to [bus 03] PCIe to PCI/PCI-X Bridge
These devices *look* like they have links going upstream, but there really
are no upstream devices.
In set_pcie_port_type(), we used the parent device to figure out which side
of a switch port has a link, so if the parent device did not exist, we
dereferenced a NULL parent pointer.
Check whether the parent device exists before dereferencing it.
Meelis observed this oops on Sparc V245 and T2000. Ben Herrenschmidt says
this is also possible on IBM PowerVM guests on PowerPC.

Current code assigns 0 to variable 'err', which makes mantis_dma_init()
to return success even if mantis_alloc_buffers() fails.
Fix it by checking the return value from mantis_alloc_buffers() and
propagating it in the case of error.

Commit 77a3c6fd90c9 ("[media] vb2: Don't WARN when v4l2_buffer.bytesused
is 0 for multiplanar buffers") uses the __WARN() macro which isn't
defined when CONFIG_BUG isn't set. This introduces a compilation
breakage. Fix it by using WARN_ON() instead.
The commit was also broken in that it merged v1 of the patch while a new
v2 version had been submitted, reviewed and acked. Fix it by
incorporating the changes from v1 to v2.

Buffers can be returned back to videobuf2 in driver's streamon handler. In
this case vb2_buffer_done() with buffer state VB2_BUF_STATE_QUEUED will
cause the driver's buf_queue vb2 operation to be called, queueing the same
buffer again only to be returned to videobuf2 using vb2_buffer_done() and so
on.
Add a new buffer state VB2_BUF_STATE_REQUEUEING which, when used as the
state argument to vb2_buffer_done(), will result in buffers queued to the
driver. Using VB2_BUF_STATE_QUEUED will leave the buffer to videobuf2, as it
was before "[media] vb2: allow requeuing buffers while streaming".

git://anongit.freedesktop.org/drm-intel into drm-fixes
Revert of a VBT parsing commit that should've been queued for drm-next,
not v4.2. The revert unbreaks Braswell among other things.
Also on Braswell removal of DP HBR2/TP3 and intermediate eDP frequency
support. The code was optimistically added based on incorrect
documentation; the platform does not support them. These are cc: stable.
Finally a gpu state fix from Chris, also cc: stable.

This patch removes TP3 support on CHV since there is no support
for HBR2 on this platform.
v2: rename the function to indicate it checks source rates (Jani)
v3: update comment to indicate TP3 dependency on HBR2 supported
hardware (Jani)

drm/i915: Allow parsing of variable size child device entries from VBT
That commit is not valid for v4.2, however it will be valid for v4.3. It
was simply queued too early.
The referenced regressing commit is just fine until the size of struct
common_child_dev_config changes, and that won't happen until
v4.3. Indeed, the expected size checks here rely on the increased size
of the struct, breaking new platforms.
