:> This warning occurs because the vxintr function does not match the
:> function type expected by pci_map_int. That is, because pci_map_int
:> expects a void func(void *) function and vxintr is a
:> void func(struct softc *).
:>
:> So, to get rid of the warning do we (a) cast the function pointer
:> in the pci_map_int() call to the correct type or (b) make the function
:> (in dev/vx/*) take a void * and then reassign the variable to a pointer
:> of the right type inside it? Or (c) some other choice that I haven't
:> thought of ?
:
:(a) as there's no overhead.... alternatively, you could try (c) ;-)
There's no overhead for b either, GCC detects the alias and optimizes
it out.
