[PATCH] watchdog: digicolor_wdt: drop unused variable

[Arnd Bergmann]

The last cleanup patch left behind an unused variable
that should have been removed as well:

drivers/watchdog/digicolor_wdt.c:121:6: error: unused variable 'ret' 
[-Werror,-Wunused-variable]

Fixes: cdad26977e3f ("watchdog: digicolor_wdt: drop warning after registering 
device")
