Alexandre Courbot 17d716e926 [media] s5p-jpeg: fix recursive spinlock acquisition ... 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_job_finish(). This is safe to do as the state of the hardware cannot change before v4l2_m2m_job_finish() is called anyway.
