From 84551afa312a19c3c26d30695552579840cc61e6 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Thu, 12 Mar 2020 12:17:12 -0700 Subject: [PATCH] drm: drm_vm: Use fallthrough; Convert /* fallthrough */ style comments to fallthrough; Convert the various uses of fallthrough comments to fallthrough; Done via script Link: https://lore.kernel.org/lkml/b56602fcf79f849e733e7b521bb0e17895d390fa.1582230379.git.joe@perches.com/ And by hand: This file has a fallthrough comment outside of an #ifdef block that causes gcc to emit a warning if converted in-place. So move the new fallthrough; inside the containing #ifdef/#endif too.
