[PATCH v2 06/12] media: ccs: Use sub-device active state

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

 



Make use of sub-device active state. In most cases the effect on need for
acquiring the mutex is non-existent as access to the driver's core data
structure still needs to be serialised.

This still removes a lot of code as the code paths for active and try
state are the same in many cases.
