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.
