Subject: [PATCH 1/8] PM / Runtime: Fetch runtime PM callbacks using a macro
Date: Thu, 20 Feb 2014 16:31:13 +0100	[thread overview]
Message-ID: <1392910280-12891-2-git-send-email-ulf.hansson@linaro.org> (raw)
In-Reply-To: <1392910280-12891-1-git-send-email-ulf.hansson@linaro.org>

While fetching the proper runtime PM callback, we walk the hierarchy of
device's power domains, subsystems and drivers.

This is common for rpm_suspend(), rpm_idle() and rpm_resume(). Let's
clean up the code by using a macro that handles this.
