Driver core documentation fixes for 5.10-rc3

Here are some small Documentation fixes for 5.10-rc3 that were fallout
 from the larger documentation update we did in 5.10-rc2.  Nothing major
 here at all, but all of these have been in linux-next and resolve build
 warnings when building the documentation files.
