Subject: [PATCH 2/6] mfd: twl-core: Refactoring for add_numbered_child()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 26 Jun 2016 13:03:59 +0200

Adjust jump targets according to the Linux coding style convention.
Another check for the variable "status" can be omitted then at the end.
