Hi Andrei,
Thank you for this, a lot of really good and needed changes are present
here that will greatly improve the driver and it takes a load off my plate.
For the patches with Fixes tags please add Cc: stable@vger.kernel.org in
v2. I'd also revisit which patch some of them fix and make sure the tags
are correct, RGB and buttons were added in separate patches.
Thanks,
Derek.
