From 6e33aceda2d82126e9d08a39e21a15be0dd00a6c Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 11 Jan 2012 15:25:20 +0530 Subject: gpio/gpio-pl061: No need of thaw and poweroff routines for hibernate pl061 uses same routines for suspend/freeze/poweroff and resume/thaw/restore. We are only saving and restoring register values on these routines. During hibernation, in freeze() we take a snapshot of gpio registers. In thaw() we don't actually need to restore these registers, as power was never shut down till now. Similarly, in poweroff() we don't need to take snapshot of these registers again, as it was done during freeze() and by now the image is already saved on disk. This patch passes poweroff() and thaw() routines as NULL to avoid this extra work done.
