Subject: [PATCH 2/2] PM / Domains: Drop unnecessary wakeup code from pm_genpd_prepare()
Date: Fri, 22 Apr 2016 10:15:55 +0200	[thread overview]
Message-ID: <1461312955-8547-3-git-send-email-ulf.hansson@linaro.org> (raw)
In-Reply-To: <1461312955-8547-1-git-send-email-ulf.hansson@linaro.org>

As the PM core already have wakeup management during the system PM phase,
it seems reasonable that genpd and its users should be able to rely on
that. Therefore let's remove this from pm_genpd_prepare().
