Subject: [PATCH] kdoc: allow dots in inline @param names

Inline kernel-doc blocks failed to parse tags containing dots (e.g.
creator.process_name in panfrost_gem.h) because the @name regex only
matched word characters. Modify the single-line pattern to match
doc_inline_sect so it includes \. and parses the same as a multi-line
comment.
