Input: cyttsp - probe from compatibles
The driver (both SPI and I2C interface) should probe from the compatible strings, cypress,cy8ctma340 etc when using device tree, not as now, where it is probing implicitly from the I2C/SPI node name "cypress,cyttsp-i2c" etc. Reviewed-by: Javier Martinez Canillas <javier@dowhile0.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Link: https://lore.kernel.org/r/20210526230352.1433537-2-linus.walleij@linaro.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
