Cover letter [PATCH 0/2] ACPI: PM: Fix two issues in acpi_device_set_power()
Hi All,
There are two, arguably minor, issues in acpi_device_set_power() that have been introduced while making the code follow the ACPI 6 recommendations.
One of them is that, if the device is in D3hot, transitioning it into D3cold only involves dropping references to some power resources and it should not involve evaluating _PS3 which may happen currently.
The second one is that it sometimes is necessary to update the power state of a device to D0 even if it was put into D0 previously, so that needs to be possible.
Please refer to the patch changelogs for details.
Thanks,
Rafael
