Subject: [PATCH 1/9] Input: mt - export MT_TOOL in input_mt_init_slot()
Date:   Tue, 29 May 2018 11:57:52 +0200
Message-Id: <20180529095800.13504-2-benjamin.tissoires@redhat.com>
In-Reply-To: <20180529095800.13504-1-benjamin.tissoires@redhat.com>
References: <20180529095800.13504-1-benjamin.tissoires@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Looks like we require users to set a tool but input_mt_init_slots() never
set the tool bit for us. Meaning that this is a useless information the
driver tries to forward.
