(void) myFunc(param1);
I did not encounter such cases in the kernel code that I read, thus far.
On the other hand, I did not saw in the kernel coding style doc anything which prohibits such usage.
If I remember, using (void) before the method name is a way to tell explicitly that this method does not return any value, but I am not sure as for the exact reasons it is used (in userspace).
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...)
