Subject: [PATCH 2/9] sh: Remove "struct arch_hw_breakpoint::name" unused field
Date:   Sun,  6 May 2018 21:19:48 +0200
Message-Id: <1525634395-23380-3-git-send-email-frederic@kernel.org>
In-Reply-To: <1525634395-23380-1-git-send-email-frederic@kernel.org>
References: <1525634395-23380-1-git-send-email-frederic@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This field seem to be unused, perhaps a leftover from old code...
