Nicholas, since you already created a patch please add you "signed-off-by" to it (see Documentation/SubmittingPatches) and post it to linux-input@vger.kernel.org (CC jkosina@suse.com). That would be the fastest way for the patch to get applied. |

The patch works. I need directions to enable hardware sleep and volume buttons on Switch 12.
