[media] mem2mem_testdev: set timestamp_type and add debug param

2013-04-25T12:48:49+00:00

While testing v4l2-ctl I noticed that this m2m driver didn't set timestamp_type
and that it spammed the kernel log with debug messages. Set timestamp_type
correctly and add debug module option to enable debug messages.

warning.

[media] mem2mem_testdev: Fix incorrect location of v4l2_m2m_release()

2012-10-06T14:50:51+00:00

v4l2_m2m_release() was placed after the return statement and outside
any of the goto labels and hence was not getting executed under the
error exit path. This patch moves it under the exit path label.

[media] mem2mem_testdev: Remove unneeded struct vb2_queue clear on queue_init()

2012-09-15T14:46:09+00:00

queue_init() is always called by v4l2_m2m_ctx_init(), which allocates
a context struct v4l2_m2m_ctx with kzalloc.
Therefore, there is no need to clear vb2_queue src/dst structs.
