V4L/DVB (12520): sh-mobile-ceu-camera: do not wait for interrupt when releasing buffers
Patch
[PATCH] video: use videobuf_waiton() in sh_mobile_ceu free_buffer()
was not quite correct. It closed a race, but introduced a potential
lock-up, if for some reason an interrupt does not come. This has been
observed in tests with tw9910. This patch safely dequeues buffers without
waiting for their completion. It also moves a buffer state assignment
under a spinlock to make it atomic with queuing of the buffer.
