Kevin Chan 81efdfd13d msm: camera: Add separate mutex for different ioctls
Real time ioctls such as buffer operations and registers
configuration updates are timing critical. Other ioctls
such as ISP stream start/stop could take longer time to
finish because the ioctl blocks until the hardware
start/stop streaming completely. Using a separate mutex
will prevent real time operations from starving and
results in framedrop.
