Re: [PATCH] Input: gpio_keys - Report wakeup events if device may wakeup

Hi Dmitry,
Yes I see Neil's changes. Thank you for letting me know.
By the way, looking at Neil's changes, would it make sense to check
for device_may_wakeup(dev) like in my patch so that the wakeup
behavior can be turned off by setting power/wakeup to disabled?
