The patch titled
Subject: lib/string_helpers: fix some kerneldoc warnings
has been removed from the -mm tree. Its filename was

Subject: lib/string_helpers: fix some kerneldoc warnings
Due to some sad limitations in how kerneldoc comments are parsed, the
documentation in lib/string_helpers.c generates these warnings:
./lib/string_helpers.c:236: WARNING: Unexpected indentation.
./lib/string_helpers.c:241: WARNING: Block quote ends without a blank line; unexpected unindent.
./lib/string_helpers.c:446: WARNING: Unexpected indentation.
./lib/string_helpers.c:451: WARNING: Block quote ends without a blank line; unexpected unindent.
./lib/string_helpers.c:474: WARNING: Unexpected indentation.
Rework the comments to obtain something like the desired result.
