The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI
monitor_present update] covered the missing update of monitor_present
flag, but this caused a regression for devices without the i915 eld
notifier. Since the old code supposed that pin_eld->monitor_present
was updated by the caller side, the hdmi_present_sense_via_verbs()
doesn't update the temporary eld->monitor_present but only
pin_eld->monitor_present, which is now overridden in update_eld().
The fix is to update pin_eld->monitor_present as well before calling
update_eld().
Note that this may still leave monitor_present flag in an inconsistent
state when the driver repolls, but this is at least the old behavior.
More proper fix will follow in the later patch.

This is Dell usb dock audio workaround.
It was fixed the master volume keep lower.
[Some background: the patch essentially skips the controls of a couple
of FU volumes. Although the firmware exposes the dB and the value
information via the usb descriptor, changing the values (we set the
min volume as default) screws up the device. Although this has been
fixed in the newer firmware, the devices are shipped with the old
firmware, thus we need the workaround in the driver side. -- tiwai]

The 'size' member of a struct firmware is passed to snd_printk with a
respective format string using the %d identifier. The 'size' member is
of type size_t, but format identifier %d indicates a signed int data
type. This patch replaces the %d format identifier with the correct %zu
format identifier for size_t data types.

On Skylake and onwards, the HD-audio controller driver needs to bind
with i915 for having the control of power well audio domain before
actually probing the codec. This leads to the load of i915 driver
from the audio driver side. But, there are systems that have no Intel
graphics but Nvidia or AMD GPU, although they still use HD-audio bus
for the onboard audio codecs. On these, loading the i915 driver is
nothing but a useless memory and CPU consumption.
A simple way to avoid it is just to look for the Intel graphics PCI
entry beforehand, and try to bind with i915 only when such an entry is
found. Currently, it assumes the PCI display class. If another class
appears, this needs to be extended (although it's very unlikely).

Changes since V1: fixed the description and added KASan warning.
In assoc_array_insert_into_terminal_node(), we call the
compare_object() method on all non-empty slots, even when they're
not leaves, passing a pointer to an unexpected structure to
compare_object(). Currently it causes an out-of-bound read access
in keyring_compare_object detected by KASan (see below). The issue
is easily reproduced with keyutils testsuite.
Only call compare_object() when the slot is a leave.

In commit c4004b02f8e5b ("x86: remove the kernel code/data/bss resources
from /proc/iomem") I was hoping to remove the phyiscal kernel address
data from /proc/iomem entirely, but that had to be reverted because some
system programs actually use it.
This limits all the detailed resource information to properly
credentialed users instead.

The PCI config access checked the file capabilities correctly, but used
the itnernal security capability check rather than the helper function
that is actually meant for that.
The security_capable() has unusual return values and is not meant to be
used elsewhere (the only other use is in the capability checking
functions that we actually intend people to use, and this odd PCI usage
really stood out when looking around the capability code.

A lot of seqfile users seem to be using things like %pK that uses the
credentials of the current process, but that is actually completely
wrong for filesystem interfaces.
The unix semantics for permission checking files is to check permissions
at _open_ time, not at read or write time, and that is not just a small
detail: passing off stdin/stdout/stderr to a suid application and making
the actual IO happen in privileged context is a classic exploit
technique.
So if we want to be able to look at permissions at read time, we need to
use the file open credentials, not the current ones. Normal file
accesses can just use "f_cred" (or any of the helper functions that do
that, like file_ns_capable()), but the seqfile interfaces do not have
any such options.
It turns out that seq_file _does_ save away the user_ns information of
the file, though. Since user_ns is just part of the full credential
information, replace that special case with saving off the cred pointer
instead, and suddenly seq_file has all the permission information it
needs.

This reverts commit c4004b02f8e5b9ce357a0bb1641756cc86962664.
Sadly, my hope that nobody would actually use the special kernel entries
in /proc/iomem were dashed by kexec. Which reads /proc/iomem explicitly
to find the kernel base address. Nasty.
Anyway, that means we can't do the sane and simple thing and just remove
the entries, and we'll instead have to mask them out based on permissions.

The ColdFire architecture specific gpio support code registers a sysfs
bus device named "gpio". This clashes with the new generic API device
added in commit 3c702e99 ("gpio: add a userspace chardev ABI for GPIOs").
The old ColdFire sysfs gpio device was never used for anything specific,
and no links or other nodes were created under it. The new API sysfs gpio
device has all the same default sysfs links (device, drivers, etc) and
they are properly populated.
Remove the old ColdFire sysfs gpio registration.

A recent change to the mbus driver added a warning printk that
prints a phys_addr_t using the %x format string, which fails in
case we build with 64-bit phys_addr_t:
drivers/bus/mvebu-mbus.c: In function 'mvebu_mbus_get_dram_win_info':
drivers/bus/mvebu-mbus.c:975:9: error: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'phys_addr_t {aka long long unsigned int}' [-Werror=format=]
This uses the special %pa format string instead, so we always
print the correct type.

Fixes for omaps against v4.6-rc1. Mostly minor fixes for the newer
SoCs with few board fixes and a fix for a long time hwmod bug:
- Fix cpsw_emac0 link type for baltos-ir5221
- Fix interrupt type for TWD
- Fix edma memcpy channel allocation for am43x
- Fix am43x-epos sycntimer32k by using the correct assigned clock
- Fix interconnect barrier for dra7
- Fix a long time hwmod bug for updating sysconfig register properly

The ARM TWD interrupt is a private peripheral interrupt (PPI) and per
the ARM GIC documentation, whether the type for PPIs can be set is
IMPLEMENTATION DEFINED. For OMAP4 devices the PPI type cannot be set and
so when we attempt to set the type for the ARM TWD interrupt it fails.
This has done unnoticed because it fails silently and because we cannot
re-configure the type it has had no impact. Nevertheless fix the type
for the TWD interrupt so that it matches the hardware configuration.

EDMA was allocating DMA channels 32 and 33 for memcpy usage, out of which
channel 33 is actually used by DES crypto engine. This bad allocation of
the channel causes a crash in the DES crypto engine, as the channel
gets configured for memcpy usage instead of hardware <-> memory DMA.
Fixed by allocating DMA channels 58 and 59 for memcpy usage (I2C0 RX/TX),
which are not used by anybody.

commit 55ee7017ee31 ("arm: omap2: board-generic: use omap4_local_timer_init
for AM437x") makes synctimer32k as the clocksource on AM43xx. By default
the synctimer32k is clocked by 32K RTC OSC on AM43xx. But this 32K RTC OSC
is not available on epos boards which makes it fail to boot.
Synctimer32k can also be clocked by a peripheral PLL, so making this as
clock parent for synctimer3k on epos boards.

came in around the same time, unfortunately this seem to have missed
initializing the barrier for DRA7 platforms - omap5_map_io was reused
for dra7 till it was split out by the last patch. barrier_init
needs to be hence carried forward as it is valid for DRA7 family of
processors as they are for OMAP5.

ARM: OMAP2+: first hwmod fix for v4.6-rc
Fix a longstanding bug in the hwmod code that could cause
hardware SYSCONFIG register values to not match the kernel's
idea of what they should be, and that could result in lower
performance during IP block idle entry.

Commit 127500ccb766f ("ARM: OMAP2+: Only write the sysconfig on idle
when necessary") talks about verification of sysconfig cache value before
updating it, only during idle path. But the patch is adding the
verification in the enable path. So, adding the check in a proper place
as per the commit description.
Not keeping this check during enable path as there is a chance of losing
context and it is safe to do on idle as the context of the register will
never be lost while the device is active.
