  [PATCH 44/44] kdbus: Cleanup kdbus_gaps_install() Sergei Zviagintsev <sergei@s15v.net> - 2015-10-08 13:40 +0200

#1242223 — [PATCH 44/44] kdbus: Cleanup kdbus_gaps_install()

 - Assign `false' to *out_incomplete directly on no-op cases.

 - Initialize `ret' with zero during declaration instead of doing it in
   the end of the function.

 - Initialize `fd' and `memfd' vars during declaration to be more
   concise.
