[PATCH v2 0/2] Add LPS0 check() for pinctrl-amd

[Mario Limonciello <superm1@kernel.org>]

From: Mario Limonciello <mario.limonciello@amd.com>

During suspend the pinctrl_amd driver disables the interrupts for
any GPIOs that are not marked as wake sources.

This however does not prevent them from changing the wake status
bit during suspend, it just stops the system from waking.

If the system wakes from hardware sleep for another reason (such
as plugging in the AC adapter) this wake bits might be active.

This could potentially cause problems with going back to hardware
sleep.  Add an extra debugging message when PM debugging is enabled
to help identify if this is happening.

  ACPI: Add missing prototype for non CONFIG_SUSPEND/CONFIG_X86 case
  pinctrl: amd: Add an LPS0 check() callback
