2021-01-25mt7601u: fix kernel crash unplugging the deviceLorenzo Bianconi1-1/+1
The following crash log can occur unplugging the usb dongle since, after the urb poison in mt7601u_free_tx_queue(), usb_submit_urb() will always fail resulting in a skb kfree while the skb has been already queued. Fix the issue enqueuing the skb only if usb_submit_urb() succeed.

2021-01-14mt7601u: check the status of device in calibrationZhi Han1-0/+3
When the usb device being plugged out, before ieee80211 gets to know the hw being removed, it gets to know that the association status changed, and thus ask for the device to do the calibration. This causes error as the hw is absent. This can be avoid by checking the status of the device before sending the calibration request to the device.
