Subject: [PATCH] iio: adc: ad7380: select REGMAP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The AD7380 driver uses generic regmap types and APIs. However, its
Kconfig entry does not select REGMAP.

As a result, AD7380 can be enabled from an allnoconfig-derived config
with SPI_MASTER=y while REGMAP remains unset, causing ad7380.o to fail
to build.
