Subject: [PATCH v3 RESEND 0/2] Add LPS0 check() for pinctrl-amd

From: Mario Limonciello <mario.limonciello@....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.

I'm resending this because kw seemed to have split the patches on
separate mailing lists and the lkp robot didn't know and reported
failures.
No changes from v3 -> v3 RESEND

Mario Limonciello (2):
  ACPI: Add missing prototype for non CONFIG_SUSPEND/CONFIG_X86 case
  pinctrl: amd: Add an LPS0 check() callback
