Subject: [PATCH 16/34] iio: ad5755: hook up of_device_id lookup to platform driver

From: Arnd Bergmann <arnd@arndb.de>

When the driver is built-in, 'make W=1' warns about an unused
ID table:

drivers/iio/dac/ad5755.c:866:34: error: 'ad5755_of_match' defined but not used [-Werror=unused-const-variable=]
  866 | static const struct of_device_id ad5755_of_match[] = {

While the data is duplicated in the spi_device_id, it's common
to use the actual OF compatible strings in the driver.

Since there are no in-tree users of plain platform devices, the
spi_device_id table could actually be dropped entirely with this.
