[PATCH] media: mt9p031: Move open subdev op init code into init_cfg

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

 



The .open subdev op is not always called soon enough to initialize
the default crop settings. Move all this initialization into .init_cfg
op instead.
