Ensure the driver gets always at least its minimum required number of buffers allocated by checking actual number of allocated buffers in vb2_reqbufs(). And free any partially allocated buffer queue with signaling an error to user space. Without this patch applications may wait forever to dequeue a filled buffer, because the hardware didn't even start after VIDIOC_STREAMON, VIDIOC_QBUF calls, due to insufficient number of empty buffers.

Not all drivers use monotonic timestamps. This patch adds a way to set the timestamp type per every queue. In addition, set proper timestamp type in drivers that I am sure that use either MONOTONIC or COPY timestamps. Other drivers will correctly report UNKNOWN timestamp type instead of assuming that all drivers use monotonic timestamps. Signed-off-by:

Define video buffer flag for the COPY timestamp. In this case the timestamp value is copied from the OUTPUT to the corresponding CAPTURE buffer. Signed-off-by:

The spec specifies that setting count to 0 in v4l2_requestbuffers should result in releasing any streaming resources and the stream ownership. Implement this. Signed-off-by:

The priv field should be set to 0. In this case the driver abused the priv field for internal housekeeping. Modify the code so priv is no longer used for that purpose. Signed-off-by:

Add device_caps support to querycap, fill in bus_info correctly and do not set the version field (let the core handle that). Also simplify the s_input ioctl. Signed-off-by:

file->private_data is needed to store the pointer to struct v4l2_fh. So use video_drvdata to get hold of the stk_camera struct. Signed-off-by:

The 417 support doesn't work. Until someone can dig into this driver to figure out why it isn't working the 417 support is disabled. Sometimes you can actually stream a bit, but very soon the whole machine crashes, so something is seriously wrong. For the record, this was not introduced by my recent changes to this driver, it was broken before that. Signed-off-by:

The g_tuner call wasn't passed on to the subdevices, g_frequency didn't check for invalid tuners and a low-level function that was expected to return 0 or a negative error returned a positive number instead, causing s_frequency to return bogus errors. Signed-off-by:
