Applied to 5.9/scsi-queue. Thanks for cleaning things up!

I do think that in general it makes little sense for low-level drivers
to document internal functions using kerneldoc. As a general approach
I would prefer to just switch drivers to '/*' or to remove stale
comments instead of trying to keep up with the "docrot" warnings.

kerneldoc cleanups are great for functions that actually have more
than one user (core code, libraries, common code used by multiple
drivers, etc.). Whereas for driver internals I would much rather
emphasize function arguments with well-chosen, descriptive names
instead of a kerneldoc "@p: pointer to a foobar" comment that will
inevitably become stale next time an interface changes.
