Subject: 6lowpan: double unlock on an error path
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=747cf6ed3dbf6200af761f5384893c3b621a484c;p=linux-beck.git

6lowpan: double unlock on an error path

We already unlocked a few lines earlier here, so we can go directly to
drop without passing through unlock.  This was introduced recently in
c5d3687f6c ('6lowpan: read data from skb safely').
