Wysocki <rafael.j.wysocki@xxxxxxxxx> Thank you for your patch for this. This looks good to me, except that I already fixed the acer-wmi.c case a couple of weeks ago, and that fiox was merged into Linus' tree already: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ef14f0e82c9b225ae19476fa5bed89d55b2a96d5 I can drop the acer-wmi.c chunks when I merge this, so there is no need to send out a new version.
