Message-Id: <1395684784-12601-1-git-send-email-sebastian.capella@linaro.org> Date: Mon, 24 Mar 2014 11:13:04 -0700 From: Sebastian Capella <sebastian.capella@...aro.org> To: linux-kernel@...r.kernel.org, linux-pm@...r.kernel.org, linaro-kernel@...ts.linaro.org Cc: Sebastian Capella <sebastian.capella@...aro.org>, Len Brown <len.brown@...el.com>, Pavel Machek <pavel@....cz>, "Rafael J. Wysocki" <rjw@...ysocki.net> Subject: [PATCH] ARM: machine_power_off should not return Add loop to prevent return from machine_power_off if pm_power_off is null or does not halt the system. This caused a panic during hibernation testing on Kirkwood Openblocks A6 board.
