Subject[PATCH AUTOSEL 5.0 002/173] media: rockchip/vpu: Add missing dont_use_autosuspend() calls
Date
From: Jonas Karlman <jonas@kwiboo.se>

[ Upstream commit 5c5b90f5cbad77dc15d8b5582efdb2e362bcd710 ]

Those calls are needed to restore a clean PM state when the probe fails
or when the driver is unloaded such that future ->probe() calls can
initialize runtime PM again.
