linux-toradex.git/include/acpi, branch v6.9-rc7 Linux kernel for Apalis and Colibri modules ACPI: bus: allow _UID matching for integer zero 2024-04-08T14:57:51+00:00 Raag Jadav raag.jadav@intel.com 2024-03-28T03:55:40+00:00 aca1a5287ea328fd1f7e2bfa6806646486d86a70 Commit b2b32a173881 ("ACPI: bus: update acpi_dev_hid_uid_match() to support multiple types") added _UID matching support for both integer and string types, which satisfies NULL @uid2 argument for string types using inversion, but this logic prevents _UID comparision in case the argument is integer 0, which may result in false positives. Fix this using _Generic(), which will allow NULL @uid2 argument for string types as well as _UID matching for all possible integer values.

Commit b2b32a173881 ("ACPI: bus: update acpi_dev_hid_uid_match() to
support multiple types") added _UID matching support for both integer
and string types, which satisfies NULL @uid2 argument for string types
using inversion, but this logic prevents _UID comparision in case the
argument is integer 0, which may result in false positives.

Fix this using _Generic(), which will allow NULL @uid2 argument for
string types as well as _UID matching for all possible integer values.

     injection code (Avadhut Naik)

     memory failure events, so they are handled differently from the
     asynchronous ones (Shuai Xue)

     (Prarit Bhargava)

     not the same as one of the real pxm values (Yuntao Wang)

   - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
     driver so as to prevent miscalculation of the values in the clock
     divider (Andy Shevchenko)

     from complaining during documentation builds (Randy Dunlap)

   - Make the ACPI button driver send wakeup key events to user space in

     the power button (Ken Xue)
