From 2cb55a2f47a3c695a0105b7fc04a3b70c3bc4e4f Mon Sep 17 00:00:00 2001 From: Yuanhan Liu Date: Tue, 16 Oct 2012 22:59:04 +0800 Subject: [PATCH] sonypi: suspend/resume 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).
