Hello Hans,

This series improves the mutex handling of the R-Car CSI-2 driver. While 
working with other drivers it have surfaced that drivers are responsible 
to serialize format configuration.

Patch 1/2 adds a bit of housekeeping to the mutex used in the driver 
while patch 2/2 adds the format serialization.

The series is based on the latest media-tree and tested on M3-N and H3 
ES2.0 without any regressions found.

Niklas Söderlund (2):
  media: rcar-csi2: Cleanup mutex on remove and fail
  media: rcar-csi2: Serialize access to set_fmt and get_fmt
