Subject: doc-rst: parse-headers: better handle comments at the source code
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=034e6c8e72afe0106e7ad3c19941053072b6a994;p=linux.git

doc-rst: parse-headers: better handle comments at the source code

We should not let comments to mangle with the symbols
parsing. Unfortunately, videodev2.h has lots of those
in the middle of enums and structs. So, we need to improve
our parser to discard them.
