There are two ways to connect the Steam Controller: directly to the USB
or with the USB wireless adapter. Both methods are similar, but the
wireless adapter can connect up to 4 devices at the same time.
The wired device will appear as 3 interfaces: a virtual mouse, a virtual
keyboard and a custom HID device.
The wireless device will appear as 5 interfaces: a virtual keyboard and
4 custom HID devices, that will remain silent until a device is actually
connected.
The custom HID device has a report descriptor with all vendor specific
usages, so the hid-generic is not very useful. In a PC/SteamBox Valve
Steam Client provices a software translation by using hidraw and a
creates a uinput virtual gamepad and XTest keyboard/mouse.
This driver intercepts the hidraw usage, so it can get out of the way
when the Steam Client is in use.

Richard Jones has reported that using med_power_with_dipm on a T450s
with a Sandisk SD7UB3Q256G1001 SSD (firmware version X2180501) is
causing the machine to hang.
Switching the LPM to max_performance fixes this, so it seems that
this Sandisk SSD does not handle LPM well.
Note in the past there have been bug-reports about the following
Sandisk models not working with min_power, so we may need to extend
the quirk list in the future: name - firmware
Sandisk SD6SB2M512G1022I - X210400
Sandisk SD6PP4M-256G-1006 - A200906

These go away when switching from med_power_with_dipm to medium_power.
This is somewhat weird as the PM830 datasheet explicitly mentions DIPM
being supported and the idle power-consumption is specified with DIPM
enabled.
There are many OEM customized firmware versions for the PM830, so for now
lets assume this is firmware version specific and blacklist LPM based on
the firmware version.

There is an issue(Errata Ref#226) that the SATA can not be
detected via SATA Port-MultiPlayer(PMP) with following
error log:
ata1.15: PMP product ID mismatch
ata1.15: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
ata1.15: Port Multiplier vendor mismatch '0x1b4b'!='0x0'
ata1.15: PMP revalidation failed (errno=-19)
After debugging, the reason is found that the value Port-x
FIS-based Switching Control(PxFBS@0x40) become wrong.
According to design, the bits[11:8, 0] of register PxFBS
are cleared when Port Command and Status (0x18) bit[0]
changes its value from 1 to 0, i.e. falling edge of Port
Command and Status bit[0] sends PULSE that resets PxFBS
bits[11:8; 0].
So it needs a mvebu SATA WA to save the port PxFBS register
before PxCMD ST write and restore it afterwards.
This patch implements the WA in a separate function of
ahci_mvebu_stop_engine to override ahci_stop_gngine.

Marvell armada37xx, armada7k and armada8k share the same
AHCI sata controller IP, and currently there is an issue
(Errata Ref#226)that the SATA can not be detected via SATA
Port-MultiPlayer(PMP). After debugging, the reason is
found that the value of Port-x FIS-based Switching Control
(PxFBS@0x40) became wrong.
According to design, the bits[11:8, 0] of register PxFBS
are cleared when Port Command and Status (0x18) bit[0]
changes its value from 1 to 0, i.e. falling edge of Port
Command and Status bit[0] sends PULSE that resets PxFBS
bits[11:8; 0].
So it needs save the port PxFBS register before PxCMD
ST write and restore the port PxFBS register afterwards
in ahci_stop_engine().
This commit allows drivers to override ahci_stop_engine
behavior for use by the Marvell AHCI driver(and potentially
other drivers in the future).

This reverts commit f0f56716fc3e5d547fd7811eb218a30ed0695605.
According to Thierry's view,
https://www.spinics.net/lists/linux-ide/msg55357.html
some hardware-specific drivers already use their own resets,
and the common reset might make a path to occur double controls of resets.
For now, revert the commit that adds reset control support to ahci-platform,
and hold until the solution is confirmed not be affect all hardware-specific
drivers.

It turns out that the Windows GPIO driver for Sunrisepoint PCH-H uses
similar bank structure than it does for Cannon Lake with the exception
that here the bank size is always 24 pins. Starting from pad group E the
BIOS/Windows GPIO numbering does not match the hardware anymore but
instead there are gaps to make each pad group ("bank") consume exactly
24 pins. Because of this Linux does not use correct pins for
GpioIo/GpioIo resources exposed by the BIOS.
This patch aligns the GPIO number space with BIOS/Windows to make sure
the same numbering scheme is used in Linux as well following what we did
already for Intel Cannon Lake.

When we dropped the custom Linux GPIO translation it resulted that the
IRQ numbers changed slightly as well. Normally this would be fine
because everyone is expected to use controller relative GPIO numbers and
ACPI GpioIo/GpioInt resources. However, there is a certain set of
Intel_Strago based Chromebooks where i8042 keyboard controller IRQ
number is hardcoded be 182 (this is corrected with newer coreboot but
the older ones still have the hardcoded Linux IRQ number). Because of
this hardcoded IRQ number keyboard on those systems accidentally broke
again.
Fix this by iteratively associating IRQ descriptors to the chip irqdomain
so that there are no gaps on those systems. Other systems are not
affected.

If the main loop in linehandle_create() encounters an error, it
unwinds completely by freeing all previously requested GPIO
descriptors. However, if the error occurs in the beginning of
the loop before that GPIO is requested, then the exit code
attempts to free a null descriptor. If extrachecks is enabled,
gpiod_free() triggers a WARN_ON.
Instead, keep a separate count of legitimate GPIOs so that only
those are freed.

Only the overlay notifier callbacks have a chance to potentially get
hold of references to those two resources, but they are not supposed to
store them beyond OF_OVERLAY_POST_REMOVE.
Document the overlay notifier API, its constraint regarding pointer
lifetime, and then remove intentional leaks of ovcs->overlay_tree and
ovcs->fdt from free_overlay_changeset.

This pretty much reverts commit 273df9635385 ("iommu/dma: Make PCI
window reservation generic") by moving the PCI window region
reservation back into the dma specific path so that these regions
doesn't get exposed via the IOMMU API interface. With this change,
the vfio interface will report only iommu specific reserved regions
to the user space.

iommu clocks are optional, so the driver should not fail if they are not
present. Instead just set the number of clocks to 0, which the clk-blk APIs
can handle just fine.

When the interrupts for a combiner span multiple registers it must be
checked if any interrupts have been asserted on each register before
checking for spurious interrupts.
Checking each register seperately leads to false positive warnings.

When the module is removed the led workqueue is destroyed in the remove
callback, before the led device is unregistered from the led subsystem.
This leads to a NULL pointer derefence when the led device is
unregistered automatically later as part of the module removal cleanup.
Bellow is the backtrace showing the problem.

Here's a fix for a long-standing issue in the visor driver, which could
have security implications. Included is also a new modem device id.
Both commits have been in linux-next for a couple of days with no

If we get an invalid device configuration from a palm 3 type device, we
might incorrectly parse things, and we have the potential to crash in
"interesting" ways.
Fix this up by verifying the size of the configuration passed to us by
the device, and only if it is correct, will we handle it.
Note that this also fixes an information leak of slab data.

broken.
Alan writes:
What you can't see just from reading the patch is that in both
cases (ehci->itd_pool and ehci->sitd_pool) there are two
allocation paths -- the two branches of an "if" statement -- and
only one of the paths calls dma_pool_[z]alloc. However, the
memset is needed for both paths, and so it can't be eliminated.
Given that it must be present, there's no advantage to calling
dma_pool_zalloc rather than dma_pool_alloc.

If the I2C adapter that the PD controller is attached to
does not support SMBus protocol, the driver needs to handle
block reads separately. The first byte returned in block
read protocol will show the total number of bytes. It needs
to be stripped away.
This is handled separately in the driver only because right
now we have no way of requesting the used protocol with
regmap-i2c. This is in practice a workaround for what is
really a problem in regmap-i2c. The other option would have
been to register custom regmap, or not use regmap at all,
however, since the solution is very simple, I choose to use
it in this case for convenience. It is easy to remove once
we figure out how to handle this kind of cases in
regmap-i2c.

Some non-compliant high-speed USB devices have bulk endpoints with a
1024-byte maxpacket size. Although such endpoints don't work with
xHCI host controllers, they do work with EHCI controllers. We used to
accept these invalid sizes (with a warning), but we no longer do
because of an unintentional change introduced by commit aed9d65ac327
("USB: validate wMaxPacketValue entries in endpoint descriptors").
This patch restores the old behavior, so that people with these
peculiar devices can use them without patching their kernels by hand.

KASAN found a use-after-free in xhci_free_virt_device+0x33b/0x38e
where xhci_free_virt_device() sets slot id to 0 if udev exists:
if (dev->udev && dev->udev->slot_id)
dev->udev->slot_id = 0;
dev->udev will be true even if udev is freed because dev->udev is
not set to NULL.
set dev->udev pointer to NULL in xhci_free_dev()
The original patch went to stable so this fix needs to be applied
there as well.

The usb_request pointer could be NULL in musb_g_tx(), where the

Move the tracepoint call to where the usb_request pointer is already
