Laurent Pinchart f6cee18858 [media] v4l: vb2: Fix race condition in vb2_fop_poll ... The vb2_fop_poll() implementation tries to be clever on whether it needs to lock the queue mutex by checking whether polling might start fileio. The test requires reading the q->num_buffer field, which is racy if we don't hold the queue mutex in the first place. Remove the extra cleverness and just lock the mutex.
