VIDIOC_S_PRIORITY is also part of the ioctls that need to check the access priority. Signed-off-by:

v4l2_device_register already sets intfdata, no need to do this again. Signed-off-by:
-
Hans Verkuil authored
Disconnecting the HDPVR caused a kernel oops if lockdep was enabled. In addition, if an app still had video0 open and attempted to call ioctl when the device was already disconnected the system would crash. Move the freeing and cleanup code to the release function: that is the right place for it since you know when you get there that nobody is using the device. Also removed usb_set_intfdata: v4l2_device_register sets this already to v4l2_dev. Signed-off-by:

v4l2_device_register already sets the usb intfdata to v4l2_dev. So use that instead. Signed-off-by:

If no signal or valid format is detected, then VIDIOC_QUERY_DV_PRESET must return 0 and set the preset to V4L2_DV_INVALID. This driver returned an error instead. Also simplified the kernel messages a bit: change v4l2_err to v4l2_dbg (not detecting a signal/valid format is not an error, so only print this info when debug == 1) and do not call v4l_fill_dv_preset_info: it's overkill to do this just for a debug message. Thanks to Mats Randgaard for bringing this to my attention. Signed-off-by:

v4l2_prio_init/open/close returned an int when in fact they would always return 0. Make these void functions. v4l2_prio_close and v4l2_prio_check pass an enum v4l2_priority as a pointer for no good reason. Replace with a normal enum v4l2_priority argument. These changes will simplify the work of moving priority handling into the v4l core. Signed-off-by:

Also removed the bogus zeroing of fmt.sliced when setting up raw VBI. This should have been removed in ivtv, but it was just copied-and-pasted into cx18. Signed-off-by:

Also removed the bogus zeroing of fmt.sliced when setting up raw VBI. Switching between raw and sliced VBI changed in 2.6.28 and this memset should have been removed at that time. It was never noticed because the bridge driver will fill in the fmt.vbi values anyway. Signed-off-by:

Currently raw and sliced vbi is setup using the video g/s_fmt ops. However, we want to split off the vbi formatting into separate ops so the first step is to create those new ops. The next step will be to convert subdev drivers and bridge drivers to use the new ops. And in the final step we can start converting the video g/s_fmt ops to the new (and more appropriate) mediabus format ops. Signed-off-by:

Only a relatively small number of video receivers and transmitters actually support VBI. So start moving the vbi specific ops to an ops struct of their own. Signed-off-by:

The UVC relative controls (exposure time, iris, focus, zoom, pan/tilt) are write-only (despite the UVC specification stating that the GET_CUR request is mandatory). Mark the controls as such, and report the related V4L2 controls V4L2_CTRL_FLAG_WRITE_ONLY. Signed-off-by:

videobuf_pages_to_sg() and videobuf_vmalloc_to_sg() happen to create a scatterlist element for every page. However, this is not true for bus addresses, so other functions shouldn't rely on the length of the scatter list being equal to nr_pages. Signed-off-by: -

While analyzing one of the videobuf patches, I noticed that videobuf_dma_sync is only used internally inside videobuf-dma-sg. So, let's remove this function, merging the code at __videobuf_dma_sync() Signed-off-by: -

For recoverable stream errors dqbuf() now returns 0 and the error flag is set instead of returning EIO. Signed-off-by:
-
Pawel Osciak authored
This flag is intended to indicate streaming errors, which might have resulted in corrupted video data in the buffer, but the buffer can still be reused and streaming may continue. Setting this flag and returning 0 is different from returning EIO. The latter should now indicate more serious (unrecoverable) errors. This patch also solves a problem with the ioctl handling code in vl42-ioctl.c, which does not copy buffer identification data back to the userspace when EIO is returned, so there is no way for applications to discover on which buffer the operation failed in such cases.
