-Subject: [PATCH 580/806] drm/v3d: Skip MMU flush if the device is currently
- off.
-
-If it's off, we know it will be reset on poweron, so the MMU won't
-have any TLB cached from before this point.  Avoids failed waits for
-MMU flush to reply.

-(cherry picked from commit 3ee4e2e0a9e9587eacbb69b067bbc72ab2cdc47b)
