This is a note to let you know that I've just added the patch titled platform/x86: ideapad-laptop: Add new _CFG bit numbers for future use to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: platform-x86-ideapad-laptop-add-new-_cfg-bit-numbers.patch and it can be found in the queue-6.1 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 1f23f01c9edd864b372c9a9d23548369db632969 Author: Eray Orçunus <erayorcunus@xxxxxxxxx> Date: Sat Oct 29 15:03:09 2022 +0300 platform/x86: ideapad-laptop: Add new _CFG bit numbers for future use [ Upstream commit be5dd7d8359de9fb22115a63f09981cdf689db4f ] Later IdeaPads report various things in last 8 bits of _CFG, at least 5 of them represent supported on-screen-displays. Add those bit numbers to the enum, and use CFG_OSD_ as prefix of their names. Also expose the values of these bits to debugfs, since they can be useful.
