[media] v4l2-ioctl: don't print the clips list

2013-06-09T00:36:21+00:00

The clips pointer is a userspace pointer, not a kernelspace pointer,
so you can't dereference the clips pointer.
Also add a few missing commas and newlines.

[media] media: v4l2-mem2mem: return for polling if a buffer is available

2013-06-03T18:30:47+00:00

The v4l2_m2m_poll() does not need to wait if there is already a buffer in
done_list of source and destination queues, but current v4l2_m2m_poll() always
waits. So done_list of each queue is checked before calling poll_wait().

The vb2_poll() does not need to wait next vb_buffer_done() if there is already
a buffer in done_list of queue, but current vb2_poll() always waits.
So done_list is checked before calling poll_wait().

[media] media: videobuf2: fix the length check for mmap

2013-04-25T12:54:00+00:00

Memory maps typically require that the buffer size to be page
aligned. Currently, two memops drivers do such alignment
internally, but videobuf-vmalloc doesn't.
Also, the buffer overflow check doesn't take it into account.
So, instead of doing it at each memops driver, enforce it at
VB2 core.
