[PATCH] 6lowpan: set peer_addr correctly again

From: Arnd Bergmann
Date: Tue Mar 28 2017 - 09:32:52 EST


A bugfix accidentally changed one line to return the peer_addr
from setup_header, causing it to become unused:

net/bluetooth/6lowpan.c: In function 'setup_header':
net/bluetooth/6lowpan.c:402:14: error: parameter 'peer_addr' set but not used [-Werror=unused-but-set-parameter]

The only user of the variable is a subsequent printk(), and
it is not otherwise initialized, so reverting the changed line
looks like the right fix.
