[PATCH] media: ov5640: use pm_runtime_force_suspend/resume for system suspend

From: Andrey Skvortsov
Date: Fri Aug 18 2023 - 13:36:02 EST


If system was suspended while camera sensor was used, data and
interrupts were still coming from sensor and that caused unstable
system. Sometimes system hanged during a resume. Use
pm_runtime_force_* helpers in order to support system suspend.
