Subject: iio: adc: dln2-adc: fix build error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5151b4afb41dd7c5e13a130efcc95326a49da8c6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iio: adc: dln2-adc: fix build error

The dln2-adc driver uses interface(s) that are controlled by the
IIO_TRIGGERED_BUFFER Kconfig symbol, so the driver needs to select
that symbol to prevent the build error.

drivers/iio/adc/dln2-adc.o: In function `dln2_adc_probe':
dln2-adc.c:(.text+0x528): undefined reference to `devm_iio_triggered_buffer_setup'
