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:

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

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