Input: zforce - fix error return code in zforce_start() 2013-12-18T16:47:39+00:00 Wei Yongjun yongjun_wei@trendmicro.com.cn 2013-12-17T16:58:18+00:00 3c4396b434613f653bf95f741a6000e671d1e011 The error code was not set if unable to set config, so the error condition wasn't reflected in the return value. Fix to return a negative error code from the error handling case instead of 0.

Input: zforce - fix possible driver hang during suspend 2013-12-15T10:53:13+00:00 Heiko Stübner heiko@sntech.de 2013-12-14T09:41:55+00:00 499e61279d0f8dc6ecf46b75479118589df58b56 handle_level_irq masks the interrupt before handling it, and only unmasks it after the handler is finished. So when a touch event happens after threads are suspended, but before the system is fully asleep the irq handler tries to wakeup the thread which will only happen on the next resume, resulting in the wakeup event never being sent and the driver not being able to wake the system from sleep due to the masked irq. Therefore move the wakeup_event to a small non-threaded handler. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
