Subject: [libata] PM callbacks should be conditionally compiled on CONFIG_PM_SLEEP
X-Git-Tag: upstream/snapshot3+hdmi~6238^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=29448ec129c5c9c7ece2ef28c72a0dafd70c8af2;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

[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).
