From 29448ec129c5c9c7ece2ef28c72a0dafd70c8af2 Mon Sep 17 00:00:00 2001 From: Yuanhan Liu Date: Tue, 16 Oct 2012 22:59:01 +0800 Subject: [libata] PM callbacks should be conditionally compiled on CONFIG_PM_SLEEP This will fix warnings like following when CONFIG_PM_SLEEP is not set: warning: 'xxx_suspend' defined but not used [-Wunused-function] warning: 'xxx_resume' defined but not used [-Wunused-function] Because SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) Only references the callbacks on CONFIG_PM_SLEEP (instead of CONFIG_PM).
