This series (choose 1 of the 2 patches) addresses an issue where the
MT7922 Bluetooth controller reset added in commit ccfc8948d7e4
("Bluetooth: btusb: mediatek: reset the controller before downloading
the fw") is causing Focusrite USB audio devices to fail to initialise
when connected during boot on kernels 6.11 and newer.
Reported by three users here:
https://github.com/geoffreybennett/linux-fcp/issues/24
Two users confirmed they have an MT7922.
I'm providing two possible solutions as I note there was a similar
change made in commit a7208610761a ("Bluetooth: btmtk: Remove
resetting mt7921 before downloading the fw"), so I'm not sure if the
reset should be reverted for the MT7925 as well as the MT7922.
Option 1: Revert the problematic reset behaviour entirely (MT7922 +
MT7925)
Option 2: Remove the reset only for the MT7922
