It does fix the commit that introduced this device support in general; I can add a Fixes line for that. I don't think anyone cares about backporting though, since there are other fairly critical devices that don't have support outright and there's still work to do before suspend/resume is generally usable on these machines. -- Hector Martin (marcan@xxxxxxxxx) Public Key: https://mrcn.st/pub
