SubjectRe: [PATCH] staging: r8188eu: Remove goto to no-op exit label

Thanks for the patch! However, A good commit message lists the why and what of
a change. I don't see a why for this commit?

FWIW (For what it's worth) I know of a couple of good reasons for this change
but you should get in the habit of putting that in the commit message. Even
for obvious things like this.

Anyway, I think this patch can stand on it's own with an updated commit
message. However, see below...

This does not look right. If netdev is not NULL why does this function skip
free_netdev()?

Fabio could you follow up with Larry and/or Phillip and see why the code does
this? To me it looks like a potential bug.

Thanks!
