Subject: [PATCH v5 1/3] Input: elan_i2c: Add comment about link between elan_i2c and hid-quirks
Date:   Thu,  6 Jun 2019 09:13:12 -0700
Message-Id: <20190606161312.47143-1-jeffrey.l.hugo@gmail.com>
In-Reply-To: <20190606161055.47089-1-jeffrey.l.hugo@gmail.com>
References: <20190606161055.47089-1-jeffrey.l.hugo@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Elan_i2c and hid-quirks work in conjunction to decide which devices each
driver will handle.  Document this link in elan_i2c as a reminder that
updates to elan_i2c need to be mirrored to hid-quirks.
