[PATCH] Input: ili210x - Set the device name according to the device model

From: Rogerio Pimentel
Date: Wed Sep 01 2021 - 15:22:54 EST


Adding the device model into the device name is useful when
applications need to set different parameters according to the
touchscreen being used, e.g. X11 calibration points.
