From 36d3295c5a0d9169bae1d40f8db92459977c2936 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Tue, 1 Oct 2019 21:53:15 +0000 Subject: [PATCH] MIPS: atomic: Fix whitespace in ATOMIC_OP macros We define macros in asm/atomic.h which end each line with space characters before a backslash to continue on the next line. Remove the space characters leaving tabs as the whitespace used for conformity with coding convention.
