Message-Id: <1384421355-4434-2-git-send-email-lee.jones@linaro.org>
Date: Thu, 14 Nov 2013 09:29:12 +0000
From: Lee Jones <lee.jones@...aro.org>
To: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org,
sameo@...ux.intel.com, micky_ching@...lsil.com.cn
Cc: linus.walleij@...aro.org, Lee Jones <lee.jones@...aro.org>
Subject: [PATCH 1/4] mfd: rtsx: Generify call-back operations in order to reduce code duplication
With only a few variations between devices, it seems silly to keep bolting
on entirely new and mostly duplicated operation structs when a generic one
could be defined and the small differences could be handled in the init
functions.
