Subject: [PATCH 1/7] teach sparse about -Waddress
Date: Wed, 22 Mar 2017 18:32:51 +0100	[thread overview]
Message-ID: <20170322173257.63019-2-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20170322173257.63019-1-luc.vanoostenryck@gmail.com>

This is used by GCC to report suspicious use of addresses.

So, reuse the same name for same or similar use.
