From 2def2625e0b49ea3ae85ae8b821979e5901c6638 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Thu, 31 Jan 2013 04:27:39 -0800 Subject: libpayload: Add more parenthesis to the endian conversion macros There weren't enough parenthesis in the macros so operations might only apply to the last part of an expression passed in as an argument.
