#1234103 — [PATCH 4/6 RESEND] mfd: arizona: Simplify adding subdevices

FromRichard Fitzgerald <rf@opensource.wolfsonmicro.com>
Date2015-09-28 14:50 +0200
Subject[PATCH 4/6 RESEND] mfd: arizona: Simplify adding subdevices
Message-ID<qdG2u-5Zh-5@gated-at.bofh.it>
The code was using a switch on the code type to execute
one of several mfd_add_devices() calls. We're already
switching on the code type earlier in the function to
select the correct patch function so we can roll selection
of the mfd device table into the same switch.
