[PATCH BlueZ 08/17] hciconfig: Fix errno handling convention

From: Anderson Lizardo <hidden>
Date: 2011-11-16 13:19:55
Subsystem: the rest · Maintainer: Linus Torvalds

Variables which are assigned to the errno variable (usually called
"err") should be negative, and "-err" should be used where a positive
value is needed.
