From 75f1133873d6a1276d3c19918b7c94975840f990 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 22 Nov 2017 12:56:45 -0800 Subject: [PATCH] genirq/matrix: Make - vs ?: Precedence explicit Noticed with a Clang build. This improves the readability of the ?: expression, as it has lower precedence than the - expression. Show explicitly that - is evaluated first.
