From ffa88e02bc67a1496fae762ad899e8f49136e7a1 Mon Sep 17 00:00:00 2001 From: Gustavo Padovan Date: Fri, 23 Nov 2012 16:50:51 -0200 Subject: [PATCH] Bluetooth: Move double negation to macros Some comparisons needs to double negation(!!) in order to make the value of the field boolean. Add it to the macro makes the code more readable.
