From 47e81e59d98b90727a02ceb486407eeed5eb8727 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Mon, 10 Jul 2017 15:51:04 -0700 Subject: linux/bug.h: correct "space required before that '-'" Correct these checkpatch.pl errors: |ERROR: space required before that '-' (ctx:OxO) |#37: FILE: include/linux/bug.h:37: |+#define BUILD_BUG_ON_ZERO(e) (sizeof(struct { int:-!!(e); })) |ERROR: space required before that '-' (ctx:OxO) |#38: FILE: include/linux/bug.h:38: |+#define BUILD_BUG_ON_NULL(e) ((void *)sizeof(struct { int:-!!(e); })) I decided to wrap the bitfield expressions that begin with minus signs in parentheses rather than insert spaces before the minus signs.
