From: Dan Carpenter <dan.carpenter@oracle.com>
[ Upstream commit d5ac225c7d64c9c3ef821239edc035634e594ec9 ]
The cam->buffers[] array has cam->num_frames elements so the > needs to
be changed to >= to avoid going beyond the end of the array. The
->buffers[] array is allocated in cpia2_allocate_buffers() if you want
to confirm.
