From 454b3a826edb5fc6d0fea3a9cfd1a5e8fc568747 Mon Sep 17 00:00:00 2001
From: Adam Jackson <ajax@redhat.com>
Date: Mon, 22 Jul 2019 13:51:06 -0400
Subject: [PATCH] hw: Rename boolean config value field from bool to boolean
"bool" conflicts with C++ (meh) and stdbool.h (ngh alright fine). This
is a driver-visible change and will likely break the build for mach64,
but it can be fixed by simply using xf86ReturnOptValBool like every
other driver.
