on a current Thinkpad X1 Yoga, this breaks resume from hibernate such
that opening the lid has (in the regular use case, see below) no effect
any more: 

The system is configured to hibernate when the lid is closed. So, the
expected behavior, which is restored by reverting this patch, is:

	close lid => system hibernates
	open lid => system resumes

With this patch, the following two cases are observed:

	1)
		close lid => system hibernates
		open lid => system stays off
		press power button => system boots and resumes

	2)
		# systemctl hibernate => system hibernates
		close lid 
		open lid => system resumes

Regards,

Thomas
