[PATCH] WARN_ONCE(): use bool for boolean flag

From: Cesar Eduardo Barros
Date: Tue Sep 29 2009 - 19:13:01 EST


Commit 70867453092297be9afb2249e712a1f960ec0a09 changed printk_once()
to use bool instead of int for its guard variable. Do the same change
to WARN_ONCE() and WARN_ON_ONCE(), for the same reasons.
