I spend some time for understanding. This is dmesg log: As I understand after registering raido0, video0, vbi0 v4l2 top layer call at the some time xc5000's function xc5000_set_analog_params here : [ 110.004059] sap [ 110.004093] sap [ 110.005390] sap each of this try load the firmware into xc5000 I see two different way add mutex to function where firmware is loaded or to xc5000_set_analog_params Both of this is working I already test it.
