NACK.
"radio" is an array of tristate values (-1, 0, 1) per installed card:
static int radio[IVTV_MAX_CARDS] = { -1, -1,
and must remain an array or you will break the driver.
Calling "radio_c" a module parameter named "radio" is wrong.
The correct fix is to reverse Rusty Russel's patch to the driver in
commit 90ab5ee94171b3e28de6bb42ee30b527014e0be7
to change the "bool" to an "int" as it should be in
"module_param_array(radio, ...)"
