[PATCH v9 09/25] gpio/omap: remove hardcoded offsets in context save/restore
From: Tarun Kanti DebBarma <hidden>
Date: 2012-02-02 17:36:30
Also in:

Subsystem:
arm port, gpio subsystem, omap gpio driver, omap2+ support, the rest · Maintainers:

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.
