media: v4l2-subdev: Follow renaming of SPI "master" to "controller"

2024-02-08T11:54:42+00:00

In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"")
some functions and struct members were renamed. To not break all drivers
compatibility macros were provided.

To be able to remove these compatibility macros push the renaming into
v4l2_spi_new_subdev().

media: mc: Add num_links flag to media_pad

2024-02-05T13:29:34+00:00

Maintain a counter of the links connected to a pad in the media_pad
structure. This helps checking if a pad is connected to anything, which
will be used in the pipeline building code.

media: v4l2-common.h: kerneldoc: correctly format return values

2024-02-05T11:57:46+00:00

Building the kerneldoc resulted in two errors:

Documentation/media/driver-api/v4l2-common:6: ./include/media/v4l2-common.h:566: ERROR: Unexpected indentation.
Documentation/media/driver-api/v4l2-common:6: ./include/media/v4l2-common.h:567: WARNING: Block quote ends without a blank line; unexpected unindent.

Format v4l2_link_freq_to_bitmap according to the kerneldoc standard.
The v4l2_fill_pixfmt_mp function also had incorrect return value
formatting, although that didn't report an error/warning, but it looked
ugly in the generated documentation. So fix that one as well.
