Merge tag 'acpi-6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI updates from Rafael Wysocki:
"These fix a couple of compiler warnings, refine an ACPI device
enumeration quirk to address a driver regression and clean up code.
Specifics:
- Make acpi_companion_match() return a const pointer and update its
callers accordingly (Andy Shevchenko)
- Move the extern declaration of the acpi_root variable to a header
file so as to address a compiler warning (Andy Shevchenko)
- Address compiler warnings in the ACPI device enumeration code by
adding a missing header file include to it (Ben Dooks)
- Refine the SMB0001 quirk in the ACPI device enumeration code so as
to address an i2c-scmi driver regression (Andy Shevchenko)
- Clean up two pieces of the ACPI device enumeration code (Andy
Shevchenko)"
