Description: Some vendor/device IDs with their corresponding flags are missing in the btusb drivers which lead to Mediatek 7921 chips not being able to work properly (i.e. wi-fi and bluetooth do not work together).

Here are the commits that are already present in v5.15-rc1:

https://github.com/torvalds/linux/commit/64832df2ac056f111b51aaebbe54a996e0fce7f1
https://github.com/torvalds/linux/commit/2cdff8ca4c8414401bcbc9701229e971797b1340

These have been tested with the following patch (on v5.13.10-arch1): https://pastebin.pl/view/raw/152ca559 and both bluetooth and wifi seem to be working.
This task depends upon
