This won't do what's expected at documentation, as Sphinx will just
fold everything into a single paragraph, like:

"0: Success -ENOENT: No match found between driver-supported link frequencies and those available in firmware. -ENODATA: No link frequencies were specified in firmware."

Maybe you could try using (untested):


* Return values:
*
* * 0: success
* * -ENOENT: No match found between driver-supported link frequencies and
* those available in firmware.
* * - ENODATA: No link frequencies were specified in firmware.

Please test it and see if the "make htmldocs" output will be what it would
be expected.

Mauro

Hans separately submitted a patch to address this better, it's here:

<URL:https://lore.kernel.org/linux-media/[email protected]/T/#t>

So this one can be ignored.
