Dear stable kernel maintainers,
I am writing to request that 3 related patches be merged to various LTS kernels. I'm not sure if it would have been preferable for me to send 3 separate emails, so please forgive me if I chose wrongly. (This is my first foray into interacting with the kernel community) :)
The patches are as follows:
1. 0cd3be51733f (HID: apple: Add support for the 2021 Magic Keyboard, 2021-10-08) 2. 346338ef00d3 (HID: apple: Swap the Fn and Left Control keys on Apple keyboards, 2020-05-15) 3. 531cb56972f2 (HID: apple: Add 2021 magic keyboard FN key mapping, 2021-11-08)
These patches have all been merged to mainline, but I believe when they were submitted, backporting may not have been considered. The Apple Magic Keyboard 2021 (Model # A2450) seems to be a popular keyboard, and without these patches, for users on certain LTS kernels that use this keyboard, the function keys do not behave as expected. e.g. Pressing the brightness down or brightness up key didn't work, and bizarrely pressing the globe/Fn key alone caused the brightness to decrease. None of the top row keys worked as expected.
I checked to see where the patches were missing and figured that it would be good to have those patches in those kernels.
I would ask that patches 1 & 3 be merged to v4.19, v5.4, v5.10, and v5.15. I would ask that patch 2 be merged to: v5.4 and v4.19.
For patch 3 to apply cleanly, it needed patch 2 to be present in the tree.
Thanks,
