From 33f82d141c897f39cd8bce592d88cb3c5af58342 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 10 Sep 2009 00:06:44 +0200 Subject: [PATCH] at_hdmac: Rework suspend_late()/resume_early() This patch reworks platform driver power management code for at_hdmac from legacy late/early callbacks to dev_pm_ops. The callbacks are converted for CONFIG_SUSPEND like this: suspend_late() -> suspend_noirq() resume_early() -> resume_noirq() Signed-off-by: Dan Williams Signed-off-by: Rafael J.
