From f56293c75bc3a2d406ff7797470a1d996af27186 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 16 Feb 2016 16:52:15 +0100 Subject: [PATCH] iio: health/afe4403: select REGMAP_SPI The newly added afe4403 driver uses the regmap facility to abstract the I2C and SPI access. However, it fails to ensure that regmap_spi is actually present: drivers/iio/built-in.o: In function `afe4403_probe': :(.text+0x9bf8): undefined reference to `__devm_regmap_init_spi' This adds a Kconfig select statement like the afe4404 I2C driver has.
