1a47de6e4a various: fix pci_set_dma_mask return value checking
pci_set_dma_mask returns a negative errno value, not a bool like
pci_dma_supported.  This of course was just a giant test for attention :)

2d7007153f [media] media: videobuf2: Restructure vb2_buffer
Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer.

Add new member variables - bytesused, length, offset, userptr, fd,
data_offset - to struct vb2_plane in order to cover all information
of v4l2_plane.
struct vb2_plane {
        <snip>
        unsigned int            bytesused;
        unsigned int            length;
        union {
                unsigned int    offset;
                unsigned long   userptr;
                int             fd;
        } m;
        unsigned int            data_offset;
}

Replace v4l2_buf with new member variables - index, type, memory - which
are common fields for buffer management.
struct vb2_buffer {
        <snip>
        unsigned int            index;
        unsigned int            type;
        unsigned int            memory;
        unsigned int            num_planes;
        struct vb2_plane        planes[VIDEO_MAX_PLANES];
        <snip>
};

v4l2 specific fields - flags, field, timestamp, timecode,
sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c
struct vb2_v4l2_buffer {
        struct vb2_buffer       vb2_buf;

        __u32                   flags;
        __u32                   field;
        struct timeval          timestamp;
        struct v4l2_timecode    timecode;
        __u32                   sequence;

b6f21dc354 [media] cx25821: remove video output support
The video output functionality never worked for this driver. Now remove the
creation of the output video nodes as well to prevent users from thinking
that video output is available, when it isn't.

To correctly implement this the video output should use vb2 as well, and
that requires rewriting the output DMA setup. But without hardware to test
I am not able to do that.

872dfcfe82 [media] bttv/cx25821/cx88/ivtv: use sg_next instead of sg++
Never use sg++, always use sg = sg_next(sg). Scatterlist entries can
be combined if the memory is contiguous but sg++ won't know about that.

As far as I can tell cx88 and ivtv are really broken because of this,
and bttv and cx25821 are OK because vb1 doesn't combine scatterlist
entries.

But regardless, sg++ should never be used, only sg_next is safe.

d52e238136 [media] v4l: Support extending the v4l2_pix_format structure
The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

f327cabf7f [media] cx25821-alsa: get rid of a __must_check warning
The hole reason for __must_check is to not ignore an error.

However, a "ret" value is used at cx25821 just to avoid the
Kernel compilation to compain about it.

That, however, produces another warning (with W=1):

drivers/media/pci/cx25821/cx25821-alsa.c: In function 'cx25821_audio_fini':
drivers/media/pci/cx25821/cx25821-alsa.c:727:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]

With the current implementation of driver_for_each_device() and
cx25821_alsa_exit_callback(), there's actually just one
very unlikely condition where it will currently produce
an error: if driver_find() returns NULL.

Ok, there's not much that can be done, as it is on a driver's
function that returns void, but it can at least print some message
if the error happens.

a877e2771a [media] cx25821: do not expose broken video output streams
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.

Original code after replace kmemdup for kstrdup, and after fix return error
code:
if (dev->input_audiofilename) {
	dev->_audiofilename = kstrdup(dev->input_audiofilename,
				      GFP_KERNEL);
	if (!dev->_audiofilename) {
		err = -ENOMEM;
		goto error;
	}
	/* Default if filename is empty string */
	if (strcmp(dev->input_audiofilename, "") == 0)
		dev->_audiofilename = "/root/audioGOOD.wav";
} else {
	dev->_audiofilename = kstrdup(_defaultAudioName,

Do this conversion for vidioc_s_crop.
Adding const for write-only ioctls was decided during the 2012 Media Workshop.

88f8472c9f [media] Fix some Makefile rules
On a few places, := were using instead of +=, causing drivers to
not compile.

While here, standardize the usage of += on all cases where multiple
lines are needed, and for obj-y/obj-m targets, and := when just one
line is needed, on <module>-obj rules.
