Subject: [PATCH v3 3/3] iio: adc: tsc2046: silent spi_device_id warning
Add spi_device_id to silent following kernel runtime warning:
"SPI driver tsc2046 has no spi_device_id for ti,tsc2046e-adc".
Signed-off-by: Oleksij Rempel <o.rempel@...gutronix.de>

changes v3:
- add missing point
- remove unneeded blank line
- assignment id at the definition line
changes v2:
- attach actual driver_data
- use spi_get_device_id fallback
