Subject: [PATCH] watchdog: smsc37b787_wdt: Mark expected switch fall-through
Date: Thu, 14 Feb 2019 14:16:01 -0600 [thread overview]
Message-ID: <20190214201601.GA13098@embeddedor> (raw)
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/watchdog/smsc37b787_wdt.c: In function ‘wb_smsc_wdt_ioctl’:
drivers/watchdog/smsc37b787_wdt.c:480:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
wb_smsc_wdt_set_timeout(timeout);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/watchdog/smsc37b787_wdt.c:482:2: note: here
case WDIOC_GETTIMEOUT:
^~~~
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.
