From b6cd7dd99a89ee2f0595bf3e62682a3cde3d4a62 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 11 Feb 2019 16:34:44 -0600 Subject: ser_gigaset: mark expected switch fall-through MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/isdn/gigaset/ser-gigaset.c: In function ‘gigaset_tty_ioctl’: drivers/isdn/gigaset/ser-gigaset.c:627:3: warning: this statement may fall through [-Wimplicit-fallthrough=] switch (arg) { ^~~~~~ drivers/isdn/gigaset/ser-gigaset.c:638:2: note: here default: ^~~~~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R. Silva Acked-by: Paul Bolle Signed-off-by: David S.
