Subject: [PATCH] checkpatch: add 6 missing types to --list-types
Git-commit: 0547fa5851c921eb1f64286f6b2ae7ab5df24e6e
Patch-mainline: v4.14-rc1
References: bsc#1051510

Unlike all other types, LONG_LINE, LONG_LINE_COMMENT and LONG_LINE_STRING
are passed to WARN() through a variable.  This causes the parser in
list_types() to miss them and consequently they are not present in the
output of --list-types.

Additionally, types TYPO_SPELLING, FSF_MAILING_ADDRESS and AVOID_BUG are
passed with a variable level, causing the parser to miss them too.

So modify the regex to also catch these special cases.
