   4 Subject: [PATCH] input: ads7846: Add missing spi_device_id strings
   5
   6 The SPI core logs error messages if a compatible string device
   7 name is not also present as an spi_device_id.
   8
   9 No spi_device_id values are specified by the driver, therefore
  10 we get 4 log lines every time it is loaded:
  11 SPI driver ads7846 has no spi_device_id for ti,tsc2046
  12 SPI driver ads7846 has no spi_device_id for ti,ads7843
  13 SPI driver ads7846 has no spi_device_id for ti,ads7845
  14 SPI driver ads7846 has no spi_device_id for ti,ads7873
  15
  16 Add the spi_device_id values for these devices.
