* [media] media/au0828: Fix IR stop, poll to not access device during disconnectShuah Khan2014-11-252-2/+17
| | | | | | | | | | | | | | | | | | | | | au0828 IR stop and poll routines continue to access device while usb disconnect is in progress. There is small window between device disconnect and usb interface is set to null. This results in filling the log with several of the following error messages. Fix it to detect device disconnect condition and avoid device access.

* [media] vb2: use dma_map_sg_attrs to prevent unnecessary syncHans Verkuil2014-11-252-10/+47
| | | | | | | | | | | | | | | | By default dma_map_sg syncs the mapped buffer to the device. But buf_prepare expects a buffer syncs for the cpu and the buffer will be synced to the device in the prepare memop. The reverse is true for dma_unmap_sg, buf_finish and the finish memop. To prevent unnecessary syncs we ask dma_(un)map_sg to skip the sync.

* [media] vb2-dma-sg: move dma_(un)map_sg hereHans Verkuil2014-11-2514-130/+64
| | | | | | | | | | | | | | | | | | | | | | | This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the prepare/finish memops. Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.

The fix is simply rearrange the call orders in uvc_delete() so that the child is removed before the parent.

| | | | | | | | The v4l2_ctrl_check() helper function is now only used in cx2341x. Move it there and make it static. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] v4l2-ctrl: move function prototypes from common.h to ctrls.hHans Verkuil2014-11-252-3/+25
| | | | | | | | For some unknown reason several control prototypes where in v4l2-common.c instead of in v4l2-ctrls.h. Move them and document them. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | Several control helper functions are no longer needed since most drivers are now converted to the control framework. So we can delete them. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
