From 976eb20e61e33dd3e7840bc26bc5d33ab9ca9c5c Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Wed, 24 Oct 2012 21:12:01 +0300 Subject: [PATCH] Bluetooth: Make use feature test macros For better code readability and avoiding simple bugs of checking the wrong byte of the features make use of feature test macros whenever possible.
