[PATCH v8 1/5] Input: elan_i2c: Export the device id whitelist

From: Jeffrey Hugo
Date: Fri Jun 21 2019 - 10:50:49 EST


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.
