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 drivers/bluetooth/btusb.c | 41 +++++++++++++++++++++++++++------------ 1 file changed, 29 insertions(+), 12 deletions(-)
