From 3612b87d181beffe2ad7ff21c46f5a5bb2c58c65 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Tue, 26 Feb 2019 11:58:35 -0600 Subject: [PATCH] watchdog: sbc60xxwdt: 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/watchdog/sbc60xxwdt.c: In function ‘fop_ioctl’: drivers/watchdog/sbc60xxwdt.c:272:3: warning: this statement may fall through [-Wimplicit-fallthrough=] wdt_keepalive(); ^~~~~~~~~~~~~~~ drivers/watchdog/sbc60xxwdt.c:275:2: note: here case WDIOC_GETTIMEOUT: ^~~~ 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.
