Disregard the word "back". Overseen this. But wouldn't be the correct fix in this case to: a) reverse the part of 90ab5ee94171b3e28de6bb42ee30b527014e0be7 to: get: static unsigned radio_c = 1; b) change the following line: module_param_array(radio, bool, &radio_c, 0644); to: module_param_array(radio, int, &radio_c, 0644); Without b) you would get a warning from the compiler again.
