2014-02-28[media] s2255drv: dynamic memory allocation efficiency fixDean Anderson1-30/+37
Driver was allocating a kernel buffer each time it was sending a command. It is better to allocate this buffer once at startup. Signed-off-by: Dean Anderson <linux-dev@sensoray.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2013-08-01[media] S2255: Removal of unnecessary videobuf_queue_is_busyDean Anderson1-7/+2
Removes unnecessary query of buffer state. The code already checks if stream is active or not. Signed-off-by: Dean Anderson <linux-dev@sensoray.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2013-03-24[media] v4l2: pass std by value to the write-only s_std ioctlHans Verkuil1-4/+4
This ioctl is defined as IOW, so pass the argument by value instead of by reference. I could have chosen to add const instead, but this is 1) easier to handle in drivers and 2) consistent with the s_std subdev operation.

2013-03-05[media] s2255: choose YUYV as the default format, not YUV422PHans Verkuil1-5/+5
The planar YUV422P is quite unusual and few if any applications support it. Instead choose the common YUYV format as the default. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-03-05[media] s2255: don't zero struct v4l2_streamparmHans Verkuil1-1/+0
All fields after 'type' are already zeroed by the core framework. Clearing the full struct also clears 'type', which causes a wrong type value to be returned. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-05[media] s2255: fix field handlingHans Verkuil1-46/+15

2013-03-05[media] s2255: fixes in the way standards are handledHans Verkuil1-22/+39
Instead of comparing against STD_NTSC and STD_PAL compare against 60 and 50 Hz formats. That's what you really want. When the standard is changed, make sure the width and height of the format are also updated to reflect the current standard. Also replace the deprecated current_norm by the g_std ioctl.

2012-09-26[media] v4l2: make vidioc_s_jpegcomp constHans Verkuil1-1/+1
Write-only ioctls should have a const argument in the ioctl op. Do this conversion for vidioc_s_jpegcomp. Adding const for write-only ioctls was decided during the 2012 Media Workshop. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
