Well, if the function actually returns nothing, in kernel code we usually
declare it as:
void myFunc( int param1)
{
/* yadda yadda yadda *.
}
Given that, what reason is there for casting the return value with (void)?
(And if the function is actually 'int myFunc ( int param1) {...}',
why are you calling it and then ignoring the return value? That's a clue
that you're abusing the API...)
