Add support to the SQ-905 driver to pass back to user space the sensor orientation information obtained from the camera during init. Modifies gspca and the videodev2.h header to create the necessary API. [mchehab@redhat.com: Changed "Output is" to "Frames are" at the comments, as suggested at LMML] Signed-off-by:

The v4l2-ioctl core checks the buffer type now by only allowing buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined. This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE buffers are allowed to be used with vidioc_g_parm. Also, ->vidioc_enum_fmt_vid_cap() is only called for VIDEO_CAPTURE buffers. There is no need to set the buffer type since it must already be the correct value. The struct which ->vidioc_querycap() is supposed to fill in is already zeroed so it's not necessary to call memset on it. Cc: Jean-Francois Moine <moinejf@free.fr> Signed-off-by:

The v4l2 core code in v4l2_ioctl will zero out the structure the driver is supposed to fill in for read-only ioctls. For read/write ioctls, all the fields which aren't supplied from userspace will be zeroed out. Zeroing code is removed from g_audio, enum_input, g_parm and gmbuf. Signed-off-by:

If a device using the gspca framework is unplugged while it is still streaming then the call that is used to free the URBs that have been allocated occurs after the pointer it uses becomes invalid at the end of gspca_disconnect. Make another cleanup call in gspca_disconnect while the pointer is still valid (multiple calls are OK as destroy_urbs checks for pointers already being NULL. Signed-off-by:

Resetting the streaming flag on disconnection prevented the URBs to be freed when streaming was active. Also, USBs cannot be killed after disconnection (oops in [usbcore] unlink1). Signed-off-by:

Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version. Signed-off-by:

ARRAY_SIZE is more concise to use when the size of an array is divided by the size of its type or the size of its first element. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @i@ @@ @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(E[...])) + ARRAY_SIZE(E) @depends on i using "paren.iso"@ type T; T[] E; @@ - (sizeof(E)/sizeof(T)) + ARRAY_SIZE(E) // </smpl> Signed-off-by:

The video device was part of the gspca device. On device disconnection while streaming, the device structure is freed at close time. In this case, the remaining close job on the video device run out of allocated memory. Signed-off-by:

The previous subdriver protection against rmmod was done via the file operations table in the device descriptor. On device disconnection while streaming, the device structure was freed at close time, and the module_put still used the module name in the freed area. Now, explicit module get/put are done on open and close. Signed-off-by:
