Subject: iio: health/afe4403: select REGMAP_SPI
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f56293c75bc3a2d406ff7797470a1d996af27186;p=deliverable%2Flinux.git

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.
