X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c9cbbb9f04f3ee27970f08d3aa6e6742a43d4ca5;p=openwrt%2Fstaging%2Fblogic.git

watchdog: wdt285: Mark expected switch fall-through

Mark switch cases where we are expecting to fall through.

Fix the following warning (Building: footbridge_defconfig arm):

drivers/watchdog/wdt285.c: In function ‘watchdog_ioctl’:
drivers/watchdog/wdt285.c:170:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   watchdog_ping();
   ^~~~~~~~~~~~~~~
drivers/watchdog/wdt285.c:172:2: note: here
  case WDIOC_GETTIMEOUT:
  ^~~~
