[media] c8sectpfe: Rework firmware loading mechanism

2016-05-09T15:57:54+00:00

c8sectpfe driver relied on CONFIG_FW_LOADER_USER_HELPER_FALLBACK option for loading its xp70 firmware. A previous commit removed this Kconfig option, as it is apparently harmful, but did not update the driver code which relied on it. This patch reworks the firmware loading into the start_feed callback. At this point we can be sure the rootfs is present, thereby removing the depedency on CONFIG_FW_LOADER_USER_HELPER_FALLBACK.

[media] c8sectpfe: Fix broken circular buffer wp management

2016-05-09T15:51:15+00:00

During the review process, a regression was intoduced in the circular buffer write pointer management. This means that wp doesn't get managed properly once the buffer becomes full. Signed-off-by: Peter Griffin Signed-off-by: Mauro Carvalho Chehab

[media] constify stv6110x_devctl structure

2016-02-01T09:31:17+00:00

The stv6110x_devctl structure is never modified, so declare it as const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media: videobuf2: Move timestamp to vb2_buffer

2015-12-18T15:53:31+00:00

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.

[media] vb2: drop v4l2_format argument from queue_setup

2015-12-18T15:48:19+00:00

The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] c8sectpfe: Combine three checks into a single if block

2015-11-19T12:10:22+00:00

The variable "tsin" was checked three times in a loop iteration of the c8sectpfe_tuner_unregister_frontend() function. This implementation detail could be improved by the combination of the involved statements into a single if block so that this variable will be checked only once there.

[media] c8sectpfe: Delete unnecessary checks before two function calls

2015-11-19T12:09:56+00:00

The functions i2c_put_adapter() and module_put() test whether their argument is NULL and then return immediately. Thus the tests around their calls are not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Mauro Carvalho Chehab
