Subject: [PATCH v3 0/4] Bluetooth: btusb: Mediatek ISO interface claim/release adjustment

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.

v2: fix commit message typo and over maximum chars per line warning.
v3: [patch 3/4] add new function btusb_mtk_disconnect for releasing MediaTek
                ISO interface
    [patch 4/4] remove redundant condition statements

Chris Lu (4):
  Bluetooth: btusb: mediatek: move Bluetooth power off command position
  Bluetooth: btusb: mediatek: add callback function in btusb_disconnect
  Bluetooth: btusb: mediatek: add intf release flow when usb disconnect
  Bluetooth: btusb: mediatek: change the conditions for ISO interface
