media: common: saa7146: allow S_STD(G_STD)

2023-04-15T07:54:35+00:00

If the requested TV standard is identical to the current

media: common: saa7146: check minimum video format size

2023-04-15T07:54:09+00:00

There was no check for the minimum width and height, so
0 values were just passed on. Fix this.

media: common: saa7146: fix compliance problems with field handling

2023-04-15T07:53:53+00:00

The initial field value of the format is ANY, which isn't allowed.
Change to INTERLACED.

VIDIOC_TRY_FMT will overwrite vv->last_field, which is an
unwanted side-effect, so drop this.

And finally vidioc_s_fmt_vid_cap didn't initialize vv->last_field
correctly.

media: common: saa7146: drop 'fmt' from struct saa7146_buf

2023-04-15T07:50:58+00:00

Use the video_fmt in saa7146_vv instead of having a pointer
to it in struct saa7146_buf.

media: saa7146: drop 'dev' and 'resources' from struct saa7146_fh

2023-04-15T07:50:36+00:00

Instead use vv->resources and video_drvdata(file) to
obtain this information.

This prepares for the vb2 conversion later when saa7146_fh is
dropped completely.
