media: cec: core: avoid recursive cec_claim_log_addrs

2024-06-12T09:39:33Z

[ Upstream commit 47c82aac10a6954d68f29f10d9758d016e8e5af1 ] Keep track if cec_claim_log_addrs() is running, and return -EBUSY if it is when calling CEC_ADAP_S_LOG_ADDRS. This prevents a case where cec_claim_log_addrs() could be called while it was still in progress.

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

2024-02-08T11:54:42Z

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

2024-02-05T13:29:34Z

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

2024-02-05T11:57:46Z

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.
