Merge branch 'acpi-bus'

rafaeljw · rafaeljw · commit 82303dd30432 · 2024-05-13T19:15:14.000+02:00
Merge changes related to _OSC handling and updates eliminating the owner
field from struct acpi_driver:

 - Make the kernel indicate support for several ACPI features that are
   in fact supported to the platform firmware through _OSC and fix
   the Generic Initiator Affinity _OSC bit (Armin Wolf).

 - Make the ACPI core set the owner value for ACPI drivers, drop the
   owner setting from a number of drivers and eliminate the owner
   field from struct acpi_driver (Krzysztof Kozlowski).
