[PATCH 5.6 077/177] drm/meson: pm resume add return errno branch

From: Greg Kroah-Hartman
Date: Mon Jun 01 2020 - 14:14:34 EST


From: Bernard Zhao <bernard@xxxxxxxx>

[ Upstream commit c54a8f1f329197d83d941ad84c4aa38bf282cbbd ]

pm_resump api did not handle drm_mode_config_helper_resume error.
This change add handle to return drm_mode_config_helper_resume`s
error number. This code logic is aligned with api pm_suspend.
After this change, the code maybe a bit readable.
