`linux-firmware-mediatek` 20260622-1 broke my Bluetooth

I have MediaTek MT7922 in my laptop. After an update, it stopped working with "No controller available".

Dmesg output: "Bluetooth: hci0: Failed to get device id (-108)"

Tried both latest kernel 7.1.5 and LTS 6.18.

I also checked rfkill and the USB power management settings. They did not cause this problem.

After downgrading linux-firmware and linux-firmware-mediatek to version 20260519-1, it works again.
