Status in linux
Hi Cameron,
Thanks for sharing your work. For patches to be merged into Ubuntu
kernel, patches need to be backport by sending SRU to ubuntu kernel
team: kernel-team at lists.ubuntu.com with specific format. This allows
reviews from broader audiences.
An example will be like
This is the patch for the 13s gen2 with the aforementioned issue
relating to volume adjustments using the keyboard function keys.
** Patch added: "Cegion-13s-gen2-sound-0.0.9-003.patch"
All patches apply against all of 5.13.x so far (with the latest being
5.13.8).
This is a duplicate of
https://bugzilla.kernel.org/show_bug.cgi?id=208555
Happy to improve these patches to a point where they could be
included.I'm posting this here, because I'm an Ubuntu user and I'd like
to see
This is the patch for the Lenovo Yoga 7 14ITL5.
