[PATCH v2 0/2] ACPI: scan: Turn off unused power resources during initialization

Hi,

Power resources that aren't associated with any devices are expected to be
turned off by the OS, but Linux only does that during resume from
suspend-to-RAM.  That turns out to be problematic, so turn them off during
system initialization too (patch [1/2]).

In addition to that, turn them off unconditionally, without checking the
current status, which should be safe and may help to work around firmware
issues (patch [2/2]).

Please refer to the patch changelogs for details.

Thanks!
