Revision e459dfeeb64008b2d23bdf600f03b3605dbb8152 authored by Andrey Ryabinin on 21 December 2015, 09:54:45 UTC, committed by David S. Miller on 22 December 2015, 20:57:54 UTC 
ipv6/addrlabel: fix ip6addrlbl_get()
 
ip6addrlbl_get() has never worked. If ip6addrlbl_hold() succeeded,
ip6addrlbl_get() will exit with '-ESRCH'. If ip6addrlbl_hold() failed,
ip6addrlbl_get() will use about to be free ip6addrlbl_entry pointer.

Fix this by inverting ip6addrlbl_hold() check.

Fixes: 2a8cc6c89039 ("[IPV6] ADDRCONF: Support RFC3484 configurable address selection policy table.")
