From 161158d7af3f67b15ee681c2b26b99ba461da9a6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 17 Apr 2020 13:21:40 +0300 Subject: iwlwifi: pcie: gen2: minor code cleanups in byte table update One line should be indented less, otherwise it looks like it belongs into the parentheses, which clearly it doesn't; also some variables can move into their respective if branches.
