From b23490cbb2027bb37287d73a050e3a9c2e4e1f39 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 22 Nov 2019 08:25:08 +0100 Subject: drm/mcde: Do not needlessly logically and with 3 The i index i always 0..3 in these statements so there is no need to tag "& 3" to clamp it to 3 here. Make the operator precedence explicit even if it's correct as it is, the paranthesis creates less cognitive stress for humans.
