platform/x86: thinkpad_acpi: Fix bitwise vs. logical warning

2021-11-17T10:04:08+00:00

[ Upstream commit fd96e35ea7b95f1e216277805be89d66e4ae962d ]

A new warning in clang points out a use of bitwise OR with boolean
expressions in this driver:

drivers/platform/x86/thinkpad_acpi.c:9061:11: error: use of bitwise '|' with boolean operands [-Werror,-Wbitwise-instead-of-logical]
        else if ((strlencmp(cmd, "level disengaged") == 0) |
                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                                                           ||
drivers/platform/x86/thinkpad_acpi.c:9061:11: note: cast one or both operands to int to silence this warning
1 error generated.

This should clearly be a logical OR so change it to fix the warning.

platform/x86: wmi: do not fail if disabling fails

2021-11-17T10:03:44+00:00

[ Upstream commit 1975718c488a39128f1f515b23ae61a5a214cc3d ]

Previously, `__query_block()` would fail if the
second WCxx method call failed. However, the
WQxx method might have succeeded, and potentially
allocated memory for the result. Instead of
throwing away the result and potentially
leaking memory, ignore the result of
the second WCxx call.

platform/x86: intel_scu_ipc: Update timeout value in comment

2021-10-27T07:59:51+00:00

[ Upstream commit a0c5814b9933f25ecb6de169483c5b88cf632bca ]

The comment decribing the IPC timeout hadn't been updated when the
actual timeout was changed from 3 to 5 seconds in
commit a7d53dbbc70a ("platform/x86: intel_scu_ipc: Increase virtual
timeout from 3 to 5 seconds") .

Since the value is anyway updated to 10s now, take this opportunity to
update the value in the comment too.

platform/x86: intel_scu_ipc: Increase virtual timeout to 10s

2021-10-27T07:59:51+00:00

[ Upstream commit 5c02b581ce84eea240d25c8318a1f65133a04415 ]

Commit a7d53dbbc70a ("platform/x86: intel_scu_ipc: Increase virtual
timeout from 3 to 5 seconds") states that the recommended timeout range
is 5-10 seconds. Adjust the timeout value to the higher of those i.e 10
seconds, to account for situations where the 5 seconds is insufficient
for disconnect command success.

platform/x86: intel_scu_ipc: Fix busy loop expiry time

2021-10-20T09:57:58+00:00

commit 41512e4dc0b84525495e784295092592adb87f1b upstream.

The macro IPC_TIMEOUT is already in jiffies (it is also used like that
elsewhere in the file when calling wait_for_completion_timeout()). Don’t
convert it using helper functions for the purposes of calculating the
busy loop expiry time.

platform/x86: amd-pmc: Add alternative acpi id for PMC controller

2021-10-20T09:57:46+00:00

commit c0d84d2c7c23e9cf23a5abdda40eeaa79eabfe69 upstream.

The Surface Laptop 4 AMD has used the AMD0005 to identify this
controller instead of using the appropriate ACPI ID AMDI0005.  Include
AMD0005 in the acpi id list.

platform/x86: touchscreen_dmi: Update info for the Chuwi Hi10 Plus (CWI527) tablet

2021-10-09T13:02:38+00:00

[ Upstream commit 196159d278ae3b49e7bbb7c76822e6008fd89b97 ]

Add info for getting the firmware directly from the UEFI for the Chuwi Hi10
Plus (CWI527), so that the user does not need to manually install the
firmware in /lib/firmware/silead.

This change will make the touchscreen on these devices work OOTB,
without requiring any manual setup.

Also tweak the min and width/height values a bit for more accurate position
reporting.
