Input: sur40 - validate number of endpoints before using them

2017-03-16T20:56:54Z

Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer or accessing memory that lie beyond the end of the endpoint array should a malicious device lack the expected endpoints.

[media] sur40: properly report a single frame rate of 60 FPS

2016-08-24T13:07:06Z

The device hardware is always running at 60 FPS, so report this both via PARM_IOCTL and ENUM_FRAMEINTERVALS.

[media] Input: sur40 - use new V4L2 touch input type

2016-08-23T19:34:29Z

Support both V4L2_TCH_FMT_TU08 and V4L2_PIX_FMT_GREY for backwards compatibility. Signed-off-by: Nick Dyer Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab Acked-by: Dmitry Torokhov

[media] sur40: drop unnecessary format description

2016-07-08T19:16:58Z

Don't fill in the format description. This is now done in the V4L2 core to ensure consistent descriptions. Signed-off-by: Hans Verkuil Acked-by: Nick Dyer Signed-off-by: Mauro Carvalho Chehab

[media] sur40: fix occasional oopses on device close

2016-07-08T19:16:57Z

Closing the V4L2 device sometimes triggers a kernel oops. Present patch fixes this. Signed-off-by: Martin Kaltenbrunner Signed-off-by: Florian Echtler Signed-off-by: Hans Verkuil Cc: # for v4.2 and up Signed-off-by: Mauro Carvalho Chehab

[media] sur40: lower poll interval to fix occasional FPS drops to ~56 FPS

2016-07-08T19:16:56Z

The framerate sometimes drops below 60 Hz if the poll interval is too high. Lowering it to the minimum of 1 ms fixes this. Signed-off-by: Martin Kaltenbrunner Signed-off-by: Florian Echtler Signed-off-by: Hans Verkuil Cc: # for v4.2 and up Signed-off-by: Mauro Carvalho Chehab

[media] vb2: replace void alloc_ctxs by struct device alloc_devs

2016-07-08T17:45:07Z

Make this a proper typed array. Drop the old allocate context code since that is no longer used. Note that the memops functions now get a struct device pointer instead of the struct device ** that was there initially (actually a void pointer to a struct containing only a struct device pointer). This code is now a lot cleaner. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Cc: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

[media] sur40: set q->dev instead of allocating a context

2016-07-08T17:35:23Z

Stop using alloc_ctx and just fill in the device pointer. Signed-off-by: Hans Verkuil Cc: Florian Echtler Signed-off-by: Mauro Carvalho Chehab

Input: sur40 - fix DMA on stack

2016-03-24T00:29:30Z

During the initialisation the driver uses a buffer on the stack for DMA. That violates the cache coherency rules. The fix is to allocate the buffer with kmalloc(). Signed-off-by: Oliver Neukum Signed-off-by: Dmitry Torokhov

[media] media: videobuf2: Move timestamp to vb2_buffer

2015-12-18T15:53:31Z

Move timestamp from struct vb2_v4l2_buffer to struct vb2_buffer for common use, and change its type to u64 in order to handling y2038 problem. This patch also includes all device drivers' changes related to this restructuring.
