Subject: docs: Special-case function-pointer parameters in kernel-doc
X-Git-Tag: v4.9-rc1~133^2~56
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5219f18aaf00f9f9ba572b3817e394043388d4ef;p=karo-tx-linux.git

docs: Special-case function-pointer parameters in kernel-doc

Add yet another regex to kernel-doc to trap @param() references separately
and not produce corrupt RST markup.
