From 9e8789ec967a2d524bcfc79c47a85d08dfbe626a Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Tue, 12 Jun 2018 16:56:54 -0700 Subject: [PATCH] drm/i915/i915_reg.h: fix the checkpatch MACRO_ARG_PRECEDENCE issues While I don't see any issue with the way these macros are being called today, let's protect them against operator precedence issues before they happen.
