Thanks for the report!
I've queued the missing part of the upstream chain for 6.6.y: 5c5e8c52e3caf
plus its follow-up fixes 67dba2c28fe0af ("Bluetooth: btmtk: Fix failed to send
func ctrl for MediaTek devices."), 099799fa9b76c5 ("Bluetooth: btmtk: Fix
wait_on_bit_timeout interruption during shutdown"), and f0c83a23fcbb42
("Bluetooth: btmtk: Fix btmtk.c undefined reference build error").

Thanks,
Sasha
