V4L/DVB: v4l: radio: si470x: fix unneeded free_irq() call

2010-09-30T10:22:41+00:00

In case of error during probe() the driver calls free_irq() function on not yet allocated irq. This patches fixes the call sequence in case of the error. Signed-off-by: Marek Szyprowski Signed-off-by: Kyungmin Park Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: v4l: videobuf: prevent passing a NULL to dma_free_coherent()

2010-09-30T10:22:22+00:00

When a driver that uses videobuf-dma-contig is used with the USERPTR memory access method a kernel oops might happen: a NULL address may be passed to dma_free_coherent(). This happens when an application calls REQBUFS and then exits without queuing any buffers. This patch fixes that bug.

V4L/DVB: ir-core: Fix null dereferences in the protocols sysfs interface

2010-09-30T10:18:37+00:00

For some cards, ir_dev->props and ir_dev->raw are both NULL. These cards are using built-in IR decoding instead of raw, and can't easily be made to switch protocols. So upon reading /sys/class/rc/rc?/protocols on such a card, return 'builtin' as the supported and enabled protocol. Return -EINVAL on any attempts to change the protocol. And most important of all, don't crash. Signed-off-by: Brian Rogers Acked-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: v4l: s5p-fimc: Fix 3-planar formats handling and pixel offset error on S5PV210 SoCs

2010-09-28T01:39:16+00:00

Fix DMA engine pixel offset calculation for 3-planar YUV formats. On S5PV210 SoCs horizontal offset is applied as number of pixels, not bytes per line.

V4L/DVB: v4l: s5p-fimc: Fix return value on probe() failure

2010-09-28T01:37:48+00:00

V4L/DVB: uvcvideo: Restrict frame rates for Chicony CNF7129 webcam

2010-09-28T01:22:13+00:00

At all frame rates except 30fps and 5fps the camera produces very dark pictures. Auto-exposure is probably disabled by the camera at all frame rates except 30fps, making them pretty unusable. Work around the problem by introducing a new RESTRICT_FRAME_RATE quirk that disables all the frame rates except the default one. Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: uvcvideo: Fix support for Medion Akoya All-in-one PC integrated webcam

2010-09-28T01:22:12+00:00

The camera requires the STREAM_NO_FID quirk. Add a corresponding entry in the device IDs list. Signed-off-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: ivtvfb: prevent reading uninitialized stack memory

2010-09-28T01:22:11+00:00

The FBIOGET_VBLANK device ioctl allows unprivileged users to read 16 bytes of uninitialized stack memory, because the "reserved" member of the fb_vblank struct declared on the stack is not altered or zeroed before being copied back to the user. This patch takes care of it. Signed-off-by: Dan Rosenberg Signed-off-by: Andy Walls Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: cx25840: Fix typo in volume control initialization: 65335 vs. 65535

The wrong value for the volume control limit, 65335 vs. 65535, prevents proper cx25840 v4l2_subdevice initialization. Reported-by: Igor M. liplianin Signed-off-by: Andy Walls Signed-off-by: Mauro Carvalho Chehab
