Hi Tristram
It would be more normal to create an ops structure
struct ksz_tag_ops {
int (*get_tag)(u8 *tag, int *port);
void (*set_tag)(void *ptr, u8 *addr, int p)
};
static const struct ksz_tag_ops ksz9477_tag_ops = {
.get_tag = ksz9477_get_tag,
.set_tag = ksz9477_set_tag,
}
and then pass this to the functions.
It might even be possible to make this more generic, use it for other
tag drivers.
