[RFC 0/3] Fixups for cancelled hibernate

["Mario Limonciello (AMD)" <superm1@kernel.org>]

Muhammad Usama Anjun's recent series for being able to cancel
the hibernate sequence [1] exposes a bug with amdgpu handling for
skipping the thaw step.

Because the thaw step is skipped in most cases, cancelling the
hibernate means that the device is left in an inconsistent
state.

To fix this allow devices to return -EBUSY and adjust the PM
core handling of this case.

Mario Limonciello (3):
  PM: Mark device as suspended if it failed to resume
  PM: Don't pass up device_resume() -EBUSY errors
  drm/amd: Return -EBUSY for amdgpu_pmops_thaw() on success
