Ideally this should be implemented with vb2, but it'll do for now. Signed-off-by:

cx25821-video-upstream_ch2.c/h is practically identical to cx25821-video-upstream.c/h so add support for ch2 into cx25821-video-upstream.c instead. After this we can replace the custom ioctls with a proper write() interface. Signed-off-by:

Drop the custom ioctls and enable the video output nodes again, this time using standard ioctls. The next step will be to provide a proper write() interface. Signed-off-by:

This driver does not have subdevices, so why call subdev ops? After removing that it became apparent that only Composite is supported as input, so remove also any reference to other inputs. Signed-off-by:

No idea why these custom ioctls exist: they have perfectly normal v4l2 counterparts which are already implemented. Signed-off-by:

- fill in colorspace - zero priv - delete unsupported formats - fix field handling - s_std should update width/height - proper mapping of width/height to valid resolutions Signed-off-by:

It is now possible to remove cx25821_fh and replace it with v4l2_fh, which in turn makes event handling and core prio handling possible. Signed-off-by:

Just remember which filehandle is streaming instead of using complicated resource masks. After this patch we can replace cx25821_fh with v4l2_fh. Signed-off-by:

Embed the video_device struct instead of allocating it. Remove some of the annoying and ugly kernel messages shown during loading and unloading of the module. Signed-off-by:

This device list is not necessary. The kernel already has all that information, so just use that instead. Also remove a bogus refcount and some dead 'private_free' code in the alsa driver. Signed-off-by:

log_status shouldn't print LOG STATUS lines, the core does that already. Fix querycap version number and add device_caps support. Signed-off-by:

Do some spring cleaning: - there are no board defines with tuners, so remove bogus tuner support. - tv standard handling has nothing to do with tuners, so keep that. - replace the deprecated current_norm by g_std. - querystd isn't implemented, so remove the ioctl. - remove a bunch of unused fields in cx25821.h Signed-off-by:

This device does not support radio or vbi, so remove anything referring to that. In addition, the driver created an 'video ioctl' node, which was unused and was effectively identical to the first video node. This bogus video node is now removed, leaving us with 8 video capture nodes and 2 video output nodes. Signed-off-by:

Skip the audio channel when registering the video nodes. This fixes a bug where that incorrectly registered 'video' node was never unregistered. Note: this bug only surfaces if the video output nodes are enabled again after the previous patch disabled them. Signed-off-by:

The cx25821 driver has support for one audio output channel and two video output channels. This is implemented in a very ugly and very evil way through a custom ioctl that passes the filename of a file containing the video data, which is then read by the driver itself using vfs. There are a number of problems with this: 1) it's very ugly and very evil (I can't say that often enough). 2) V4L2 supports video output, so why not use that? 3) it's very buggy, closing the filehandle through which you passed the ioctl will oops the kernel. 4) it's a nasty security leak since this allows you to load any file in the system as a video or audio source, so in theory you can output /etc/passwd to audio or video out and record & decode it on another device. Because of all these issues we no longer register those output video nodes. Signed-off-by:

Since rc_unregister_device() frees its argument, the subsequently call to rc_free_device() on the same variable will cause a double free bug. Fix by set argument to NULL, thus when fall through to rc_free_device(), nothing will be done there. Signed-off-by:
