I'm sorry for top-posting, but something wrong with email quoting. I'm using here gmail, it might not recognize message properly. So, please fix the subject line to have a prefix, in your case "platform/x86: ideapad-laptop: ...". Add to the commit message what you explained me and put a link to that comment. And resend new version with all maintainers included (there is a script scripts/get_maintainer.pl to help with the list of maintainers).

Some of the drivers do sysfs, but ideapad does not. For ideapad, under Xorg, it generates hotkey events. And the hotkey event are going to work under Xorg only. What about Wayland/Mir ? We also aren't sure, if the keycodes that it sends, are uniform across all Yoga variants. -- With Best Regards, Andy Shevchenko
