staging: rtl8192u: fix comments in r819xU_cmdpkt.c
This patches fixes comments by: - replacing // comments with /**/ comments - removing unnecessary comments (trailing comments with the function name, comments stating date/author when they are placed inside the function definition) - fixing internal alignment Signed-off-by: Xenia Ragiadakou <burzalodowa@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
