Subject: [PATCH 04/10] arm64: debug: Rename addr parameter for non-watchpoint exception hooks
Date: Fri,  1 Mar 2019 13:28:03 +0000	[thread overview]
Message-ID: <20190301132809.24653-5-will.deacon@arm.com> (raw)
In-Reply-To: <20190301132809.24653-1-will.deacon@arm.com>

Since the 'addr' parameter contains an UNKNOWN value for non-watchpoint
debug exceptions, rename it to 'unused' for those hooks so we don't get
tempted to use it in the future.
