The condition wouldn't have previously caused -ENOENT to be returned if
dev was NULL. The proper condition should be if (!dev || !dev->netdev).

The 6lowpan.c file was missing an #include statement for 6lowpan.h.
Without it we get the following type of warnings:

net/bluetooth/6lowpan.c:320:5: warning: symbol 'bt_6lowpan_recv' was not declared. Should it be static?
net/bluetooth/6lowpan.c:737:5: warning: symbol 'bt_6lowpan_add_conn' was not declared. Should it be static?

This is initial version of
http://tools.ietf.org/html/draft-ietf-6lo-btle-00

By default the 6LoWPAN support is not activated and user
needs to tweak /sys/kernel/debug/bluetooth/hci0/6lowpan
file.

The kernel needs IPv6 support before 6LoWPAN is usable.
