Subject: [PATCH v2] iio: adc: ad7380: select REGMAP
Date: Tue, 2 Jun 2026 16:45:39 +0000 [thread overview]
Message-ID: <20260602164539.1541685-1-sam.moelius@trailofbits.com> (raw)
From: Samuel Moelius <samuel.moelius@trailofbits.com>
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.
Fixes: b095217c104b ("iio: adc: ad7380: new driver for AD7380 ADCs")
