Overseen this. But wouldn't be the correct fix in this case to:
a) reverse the part of 90ab5ee94171b3e28de6bb42ee30b527014e0be7 to get:
static unsigned int 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.
