[PATCH 2/3] drm/bridge: ps8640: Print an error if VDO control fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Print an error message inside ps8640_bridge_vdo_control() function when
it fails so we can simplify a bit the callers, they will only need to
check the error code.
