Subject: [PATCH v2 2/8] arm64: debug: Rename addr parameter for non-watchpoint exception hooks
Date: Fri, 5 Apr 2019 13:40:42 +0100 [thread overview]
Message-ID: <20190405124048.3287-3-will.deacon@arm.com> (raw)
In-Reply-To: <20190405124048.3287-1-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.
