When two drivers don't support all the same profiles the legacy interface only exports the common profiles. This causes problems for cases where one driver uses low-power but another uses quiet because the result is that neither is exported to sysfs. To allow two drivers to disagree, add support for "hidden choices". Hidden choices are platform profiles that a driver supports to be compatible with the platform profile of another driver. Fixes: 68883474 ("ACPI: platform_profile: Allow multiple handlers") Reported-by:
