+Subject: [PATCH] input: ads7846: Add missing spi_device_id strings
+
+The SPI core logs error messages if a compatible string device
+name is not also present as an spi_device_id.
+
+No spi_device_id values are specified by the driver, therefore
+we get 4 log lines every time it is loaded:
+SPI driver ads7846 has no spi_device_id for ti,tsc2046
+SPI driver ads7846 has no spi_device_id for ti,ads7843
+SPI driver ads7846 has no spi_device_id for ti,ads7845
+SPI driver ads7846 has no spi_device_id for ti,ads7873
+
+Add the spi_device_id values for these devices.
