be replaced by a call to usb_mtp_object_free.

Tried to cherry-pick this one for 4.0 (I think we should leave 2/2 to
4.1 at this point).  Doesn't apply to master, seems to depend on a
not-yet merged patch.  Can you re-post this one and the depending patch
please?

thanks,

I forgot to skip 3/3, but I will remember to post it again as a single
patch if it's easier for you that way.
