snd_usb_find_clock_source and snd_usb_find_clock_selector are helper macros that look at an entity id and validate that this entity id is in fact a clock source or a clock selector. The present comments inside __uac_clock_find_source give the reader the impression we're looking for an entity id.

We're looking for an entity id indeed, the clock source, but since __uac_clock_find_source is recursive, we're also looking *at* the entity ids, in the search for the one clock source.

Fix the comment so we don't give readers a wrong idea.
