From 025a06c1104cd8995646b761d117816b5f28c873 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Wed, 25 Mar 2020 22:21:15 +0100 Subject: mtd: Convert fallthrough comments into statements Use Joe Perches cvt_fallthrough.pl script to convert /* fallthrough */ comments (and its derivatives) into a fallthrough; statement. This automatically drops useless ones. Do it MTD-wide.
