# MT7925 Bluetooth firmware mishandles USB autosuspend remote-wakeup events:
# a wake-up sequence after autosuspend corrupts the controller's HW/FW state
# machine, leaving the USB device unable to answer descriptor reads (error -110).
# Recovery from that state requires a hard power cycle (cold boot), not just
# a soft reboot.
#
# Refs: Red Hat #2372880, Ubuntu LP #2092746, upstream btmtk pm cleanup patches.
