Documentation/driver-api: fixed spelling mistakes

2025-02-13T16:44:30+00:00

Fixed some spelling mistakes identified by misspell tool.
The example code in Documentation/driver-api/nvdimm/nvdimm.rst contained a
misspelled identifier (paramaters instead of parameters).
This typo would have caused a compilation error if copied as-is.

media: Documentation: mc: Replace deprecated graph walk API

2024-08-24T22:42:01+00:00

The graph walk API has been deprecated in commit eac564de0915 ("media:
mc: entity: Add entity iterator for media_pipeline") in favour of
pipelien iterators, but the MC documentation hasn't been updated
accordingly. It still documents the deprecated API as the only option.
Fix it by dropping the deprecated function, and documenting the new API.
