Add function names to the kernel-doc of some functions and upgrade
descriptions of some parameters in it.
The warnings were found by running scripts/kernel-doc, which is
caused by using 'make W=1'.

Thanks, we care only about the argument list that the kdoc format and
script can verify, the rest is not really useful for internal functions
and makes it less pleasant to read. The script will report that though
but we won't fix it, rather would like to see the script updated to
skip that.
