Bluetooth: btusb: Fix atheros firmware download error
Move usb_autopm_get_interface() ahead of setup_on_usb() to prevent device from sending usb control message in usb suspend mode. The error message is as below: [ 83.944103] btusb 1-2:1.1: usb_suspend_interface: status 0 [ 83.944107] btusb 1-2:1.0: usb_suspend_interface: status 0 [ 83.960132] usb 1-2: usb auto-suspend, wakeup 0 [ 83.976156] usb 1-2: usb_suspend_device: status 0 [ 83.976162] usb 1-2: usb_suspend_both: status 0 [ 298.689106] Bluetooth: hci0 [ 298.689399] Bluetooth: hci0: Failed to access otp area (-113) Signed-off-by: Ethan Hsieh <ethan.hsieh@canonical.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
