Subject: [PATCH] input:gpio-key: set IRQF_NO_SUSPEND for wake capable key
Date: Fri, 18 Sep 2015 00:06:59 +0800 [thread overview]
Message-ID: <1442506019-13687-1-git-send-email-qipeng.zha@intel.com> (raw)
When wakeup attribute is set, GPIO key is supposed to wake up
the system from system sleep state, So set IRQF_NO_SUSPEND
flag to keep IRQ enabled during suspend.
