Given the following definitions from s2255drv.c #define LINE_SZ_4CIFS_NTSC 640 #define LINE_SZ_2CIFS_NTSC 640 #define LINE_SZ_1CIFS_NTSC 320 and #define LINE_SZ_4CIFS_PAL 704 #define LINE_SZ_2CIFS_PAL 704 #define LINE_SZ_1CIFS_PAL 352 f->fmt.pix.width possible values can be reduced to LINE_SZ_4CIFS_NTSC or LINE_SZ_1CIFS_NTSC. This patch removes unneeded if else blocks in vidioc_try_fmt_vid_cap function. This issue was detected by using the Coccinelle software. Signed-off-by:

Currently the driver signals the source change event only in case of a midstream resolution change, however the initial format detection is also defined as a source change by the V4L2 codec API specification. Fix this by signaling the event after the initial header is parsed as well. Signed-off-by:

Quoting the original report: It looks like there is a double-free vulnerability in Linux usbtv driver on an error path of usbtv_probe function. When audio registration fails, usbtv_video_free function ends up freeing usbtv data structure, which gets freed the second time under usbtv_video_fail label. usbtv_audio_fail: usbtv_video_free(usbtv); => v4l2_device_put(&usbtv->v4l2_dev); => v4l2_device_put => kref_put => v4l2_device_release => usbtv_release (CALLBACK) => kfree(usbtv) (1st time) usbtv_video_fail: usb_set_intfdata(intf, NULL); usb_put_dev(usbtv->udev); kfree(usbtv); (2nd time) So, as we have refcounting, use it Reported-by:Yavuz, Tuba <tuba@ece.ufl.edu> Signed-off-by:

While the h.264 standard only allows up to 16 reference frames, the CODA firmware needs two more buffers: one to hold the currently decoded frame and one for the display frame. Adding the framebuffer needed by the driver for VDOA operation brings the total to a maximum of 19 internal framebuffers. Lift the current maximum of 17 internal framebuffers to allow playback of high profile streams that require more than 14 reference frames. Signed-off-by:

After the move of videobuf2 into the common directory, selecting the au0828 driver with CONFIG_V4L2 disabled started causing a link failure, as we now attempt to build videobuf2 but it still requires v4l2: ERROR: "v4l2_event_pending" [drivers/media/common/videobuf/videobuf2-v4l2.ko] undefined!

ERROR: "v4l_vb2q_enable_media_source" [drivers/media/common/videobuf/videobuf2-core.ko] undefined! We want to be able to build the core au0828 support without V4L2, so this makes the 'select' conditional on V4L2, and refines the dependencies in VIDEO_AU0828_V4L2 so it can only be enabled in the exact conditions that have VIDEOBUF2_VMALLOC reachable.

ov7670 driver supports two optional properties supplied through platform data, but currently does not support any standard video interface property. Add support through OF parsing for 2 generic properties (vsync and hsync polarities) and for one custom property already supported through platform data to suppress pixel clock output during horizontal blanking. While at there, check return value of register writes in set_fmt function and rationalize spacings. Signal polarities and pixel clock blanking verified through scope and image capture. Signed-off-by:

The ov9650 driver currently only supports legacy platform data probe. This change adds device tree probing. There has been an attempt to add device tree support for ov9650 driver by Hugues Fruchet as a part of the patchset that adds support of OV9655 camera (http://www.spinics.net/lists/linux-media/msg117903.html), but it wasn't merged into mainline because creating a separate driver for OV9655 is preferred. This is very similar to Hugues's patch, but not supporting new device. Cc: Jacopo Mondi <jacopo@jmondi.org> Cc: H.

Previously, the sensor, with default settings, was outputting SOF without data. This results in frame sync error on the receiver side. Now, configure the sensor to output SOF with MIPI data for all frames. This avoids possible null first frame on the bus. Signed-off-by:
