PM: hibernate: Add stub for pm_hibernate_is_recovering()
Randy reports that amdgpu fails to compile with the following error:
ERROR: modpost: "pm_hibernate_is_recovering" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
This happens because pm_hibernate_is_recovering() is only compiled when
CONFIG_PM_SLEEP is set. Add a stub for it so that drivers don't need
to depend upon CONFIG_PM.
