Description: net/llc: avoid BUG_ON() in skb_orphan()
References:
Notes:
bwh> The upstream commit refers to an added assertion in 3.12, but the
bwh> purpose of that assertion was to catch potential UAF cases so I
bwh> assume this bug could result in a UAF in 3.2. Note that this bug
bwh> is in the obscure llc2 module, not the basic llc support used by
bwh> some other protocols.
