v4l2_m2m_job_finish(), which is called from the interrupt handler with
slock acquired, can call the device_run() hook immediately if another
context was in the queue. This hook also acquires slock, resulting in
a deadlock for this scenario.
Fix this by releasing slock right before calling v4l2_m2m

The driver allocates the spinlock but not initialize it.
Use spin_lock_init() on it to initialize it correctly.

The conversion from soc_camera omitted a correct handling of the clock

Hi!
For focus to be useful, we need autofocus implmented
somewhere. Unfortunately, v4l framework does not seem to provide good
place where to put autofocus. I believe, long-term, we'll need some
kind of "video server" providing this kind of services.
Anyway, we probably don't want autofocus in ke
