From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Rafael J. Wysocki" Date: Sun, 14 Aug 2011 14:04:44 +0000 Subject: [PATCH] PM / Domains: Fix build for CONFIG_PM_RUNTIME unset Message-Id: <201108141604.44304.rjw@sisk.pl> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Linux PM mailing list Cc: LKML , linux-sh@vger.kernel.org From: Rafael J. Wysocki Function genpd_queue_power_off_work() is not defined for CONFIG_PM_RUNTIME, so pm_genpd_poweroff_unused() causes a build error to happen in that case. Fix the problem by making pm_genpd_poweroff_unused() depend on CONFIG_PM_RUNTIME too. Signed-off-by: Rafael J. Wysocki --- This is 3.1 material if no one objects.
