Subject: [PATCH v7 1/5] Input: elan_i2c: Export the device id whitelist
Date: Thu, 20 Jun 2019 07:33:18 -0700	[thread overview]
Message-ID: <20190620143318.11880-1-jeffrey.l.hugo@gmail.com> (raw)
In-Reply-To: <20190620142801.11827-1-jeffrey.l.hugo@gmail.com>

Elan_i2c and hid-quirks work in conjunction to decide which devices each
driver will handle.  Elan_i2c has a whitelist of devices that should be
consumed by hid-quirks so that there is one master list of devices to
handoff between the drivers.  Put the ids in a header file so that
hid-quirks can consume it instead of duplicating the list.
