[PATCH 18/19] mac80211: make ieee80211_new_mesh_header return unsigned

From: Andrzej Hajda
Date: Thu Sep 24 2015 - 10:02:33 EST

The function returns always non-negative values.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].
