using sizeof operator

[Sukrit Sangwan]

There are instances in the code where sizeof(*ptr) is used. e.g.
in net/802/garp.c
          const struct garp_msg_hdr *gm;
          if (!pskb_may_pull(skb, sizeof(*gm)))
 return -1;
i want to ask is there any sense in using sizeof(struct garp_msg_hdr)
instead of sizeof(*gm) in the above example.

Thanks
