From: Hsin-chen Chuang <chharry@xxxxxxxxxxxx>
The function enters infinite recursion if the HCI device doesn't support
GPIO reset: btusb_reset -> hdev->reset -> vendor_reset -> btusb_reset...
btusb_reset shouldn't call hdev->reset after commit f07d478090b0
("Bluetooth: Get rid of cmd_timeout and use the reset callback")
Fixes: f07d478090b0 ("Bluetooth: Get rid of cmd_timeout and use the reset callback")
