From patchwork Tue Oct 16 14:59:01 2012 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [1/5] ata: suspend/resume callbacks should be conditionally compiled on CONFIG_PM_SLEEP Date: Tue, 16 Oct 2012 04:59:01 -0000 From: Yuanhan Liu X-Patchwork-Id: 191811 Message-Id: <1350399545-11179-1-git-send-email-yuanhan.liu@linux.intel.com> To: linux-kernel@vger.kernel.org Cc: Yuanhan Liu , Jeff Garzik , Viresh Kumar , linux-ide@vger.kernel.org, Fengguang Wu 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).
