[PATCH] watchdog: document watchdog_init_timeout() wdd parameter

[Corentin Labbe]

All parameters of watchdog_init_timeout() are documented with exception
of wdd, thus generating a build warning.

This patch document it and so remove the following build warning:
drivers/watchdog/watchdog_core.c:113: warning: No description found for parameter 'wdd'
