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.
