[PATCH 0/4] Bluetooth: btusb: Mediatek ISO interface cliam/release adjustment

[Chris Lu]

MediaTek performs some test on the platform which can support LE audio and
ISO data transmission with kernel driver. We found the additional interface
claim and release flow issue need some adjustment.

These patches mainly add a callback function within the usb_disconnect function
to prevent a kernel panic caused by interfaces not being released when the BT USB
dongle is physically removed. Additionally, the condition for claiming/releasing
ISO usb interface have also been adjusted to make driver works as expected.

Chris Lu (4):
  Bluetooth: btusb: mediatek: move Bluetooth power off in
    btusb_mtk_shutdown
  Bluetooth: btusb: add callback function in btusb_disconnect
  Bluetooth: btusb: mediatek: add intf release flow in usb disconnect
  Bluetooth: btusb: mediatek: change the conditions for
    claiming/releasing iso interface
