Hello Florian,

No, he didn't. That's why he wrote "Note that this change is
only compile tested as next doesn't boot on my test machine (because of
https://git.kernel.org/linus/b3574f579ece24439c90e9a179742c61205fbcfa)
and 6.1 (which is the other kernel I have running) doesn't know about
.wol_enabled. I don't want to delay this fix until I bisected this new
issue." in the mail containing the patch.

The issue in next is resolved, but I didn't come around to test this
patch yet.

Best regards
Uwe
