<id>urn:sha1:3de93e6ed2df6521e3f68fb45eec0bb4fe1bb218</id>
<content type='text'>
On ACPI boards, when we cannot get the GPIOs to do a reset ourselves
if necessary, call acpi_device_fix_up_power() to force the ACPI _PS0
method to run.

On some devices without proper GPIO descriptions this will reset
the touchscreen for us and this may be necessary for us to be able
to communicate to the touchscreen at all.

Specifically on an Aya Neo Next this change will cause the _PS0()
ACPI function to call INIT() which does:

            Method (INIT, 0, Serialized)
            {
                TP_I = 0x00A50000
                TP_R = 0x00A50000
                Sleep (0x0A)
                TP_I = 0x00E50000
                Sleep (One)
                TP_R = 0x00E50000
                Sleep (0x06)
                TP_I = 0x00A50000
                Sleep (0x3C)
                TP_I = 0x00041800
            }

On older kernels the ACPI core assumed a power-on was necessary by itself
and would run _PS0 before our probe function runs, which can be seen from
the GPIO pin ctrl registers in /sys/kernel/debug/gpio which match
the above hex values with older kernels.

With newer kernels before this change the GPIO pin ctrl registers do not
match, indicating INIT() has not run and probing the touchscreen fails.

This change makes Linux run _PS0() again fixing the touchscreen not working
on the Aya Neo Next.

wm97xx_remove() returns zero unconditionally. To prepare changing the
prototype for platform remove callbacks to return void, make it explicit
that wm97xx_mfd_remove() always returns zero.

The prototype for wm97xx_remove cannot be changed, as it's also used as
a plain device remove callback.

Add a sanity check on the device id-table driver_info field to make sure
we never access a type structure (and function pointers) outside of the
device info array (e.g. if someone fails to ifdef a device-id entry).

Note that this also suppresses a compiler warning with -Warray-bounds
(gcc-11.3.0) when compile-testing the driver without enabling any of
the device type Kconfig options:

    drivers/input/touchscreen/usbtouchscreen.c: In function 'usbtouch_probe':
    drivers/input/touchscreen/usbtouchscreen.c:1668:16:warning: array subscript &lt;unknown&gt; is outside array bounds of 'struct usbtouch_device_info[0]' [-Warray-bounds]
     1668 |         type = &amp;usbtouch_dev_info[id-&gt;driver_info];

Commit 223f61b8c5ad ("Input: soc_button_array - add Lenovo Yoga Tablet2
1051L to the dmi_use_low_level_irq list") added the 1051L to this list
already, but the same problem applies to the 1051F. As there are no
further 1051 variants (just the F/L), we can just DMI match 1051.

Tested on a Lenovo Yoga Tablet2 1051F: Without this patch the
home-button stops working after a wakeup from suspend.

The bcm5974 driver does the allocation and dma mapping of the usb urb
data buffer, but driver does not set the URB_NO_TRANSFER_DMA_MAP flag
to let usb core know the buffer is already mapped.

usb core tries to map the already mapped buffer, causing a warning:
"xhci_hcd 0000:00:14.0: rejecting DMA map of vmalloc memory"

Fix this by setting the URB_NO_TRANSFER_DMA_MAP, letting usb core
know buffer is already mapped by bcm5974 driver

Pull USB / Thunderbolt updates from Greg KH:
 "Here is the "big" set of USB and Thunderbolt driver changes for
  5.18-rc1. For the most part it's been a quiet development cycle for
  the USB core, but there are the usual "hot spots" of development
  activity.

  Included in here are:

   - Thunderbolt driver updates:
       - fixes for devices without displayport adapters
       - lane bonding support and improvements
       - other minor changes based on device testing

   - dwc3 gadget driver changes.

     It seems this driver will never be finished given that the IP core
     is showing up in zillions of new devices and each implementation
     decides to do something different with it...

   - uvc gadget driver updates as more devices start to use and rely on
     this hardware as well

   - usb_maxpacket() api changes to remove an unneeded and unused
     parameter.

   - usb-serial driver device id updates and small cleanups

   - typec cleanups and fixes based on device testing

   - device tree updates for usb properties

   - lots of other small fixes and driver updates.

  All of these have been in linux-next for weeks with no reported
  problems"
