using sizeof operator

[Sukrit Sangwan <sukritsangwan@xxxxxxxxx>]

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
