Thanks Rikka for the updates from tuxedo!

Hi, I created this patch for the 6.16 kernel and it runs very well on my machine.

@eniac I have tried to local patch myself based on the EndeavourOS patching to build....failed miserably

@wrdn I'm using it on EndeavourOS and it works here. Maybe try asking on the CachyOS forum.
