[PATCH 1/4] media: v4l: Simplify dev_debug flags

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

 



In preparation to cleanup the debug logic, simplify the dev_debug
usage. In particular, make sure that a single flag is used to
control each debug print.

Before this commit V4L2_DEV_DEBUG_STREAMING and V4L2_DEV_DEBUG_FOP
were needed to enable read and write debugging. After this commit
only the former is needed.
