Subject: [PATCH v9 09/25] gpio/omap: remove hardcoded offsets in context save/restore
Date: Thu, 2 Feb 2012 23:00:35 +0530 [thread overview]
Message-ID: <1328203851-20435-10-git-send-email-tarun.kanti@ti.com> (raw)
In-Reply-To: <1328203851-20435-1-git-send-email-tarun.kanti@ti.com>
It is not required to use hard-coded offsets any more in context save and
restore functions and instead use the generic offsets which have been correctly
initialized during device registration.
