Raising an old thread, I pulled this series into Fedora rawhide and while it worked for Lenovo Yoga we received a report that it caused a regression on the Dell Inspiron 7559 (see https://bugzilla.redhat.com/show_bug.cgi?id=1275718#c27) . I haven't asked the reporter about bisecting to see which patch broke it. Were there any known follow up patches?
Thanks, Laura
