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.
|
|
