[PATCH 2/4] drm/bridge: anx7625: Use pm_runtime_force_suspend(resume)

From: Hsin-Yi Wang
Date: Wed Jun 29 2022 - 12:06:23 EST


There's no need to check for IRQ or disable it in suspend.

Use pm_runtime_force_suspend(resume) to make sure anx7625 is powered off
correctly. Make the system suspend/resume and pm runtime suspend/resume
more consistant.
