Re: [PATCH v2] Input: ili210x - Set the device name according to the device model

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.

Changes since v1: Get the device ID from touchscreen controller
instead of driver's device list.
