From a2988afe7cc315a045aeb9b4c38df473e2d80213 Mon Sep 17 00:00:00 2001 From: kevans Date: Tue, 3 Dec 2019 02:30:52 +0000 Subject: [PATCH] syscons.c: clang-format pass to reduce style inconsistencies This was purely automatically massaged... some parts are still imperfect, but this is close enough to make it more readable/easy to work on. Unfortunately the vt/syscons/kdb situation slightly complicates changes to tty locking, so some work will need to be done to remediate that. --- sys/dev/syscons/syscons.c | 5915 +++++++++++++++++++------------------ 1 file changed, 3014 insertions(+), 2901 deletions(-) diff --git a/sys/dev/syscons/syscons.c b/sys/dev/syscons/syscons.c index 278c3c82b67a..dc43c0d6306d 100644 --- a/sys/dev/syscons/syscons.c +++ b/sys/dev/syscons/syscons.c @@ -65,13 +65,13 @@ __FBSDID("$FreeBSD$");
