Hello Greg,

I found that rtw_get_ie is called 62 times and the passed argument
can be declared as sint, uint, u32, u8 and probably a couple more.
I'll drop this patch for now and check more carefully if this fix
would require more changes, as changing the argument type wouldn't
solve the warning described in the commit.
