From: Jonathan Cameron <[email protected]> commit 121875b28e3bd7519a675bf8ea2c2e793452c2bd upstream.
Seems that there are config combinations in which this driver gets enabled and hence selects the MFD, but with out HAS_IOMEM getting pulled in via some other route. MFD is entirely contained in an if HAS_IOMEM block, leading to the build issue in this bugzilla. https://bugzilla.kernel.org/show_bug.cgi?id=209889 Cc: <[email protected]> Signed-off-by: Jonathan Cameron <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]> --- drivers/iio/adc/Kconfig | 1 + 1 file changed, 1 insertion(+) --- a/drivers/iio/adc/Kconfig +++ b/drivers/iio/adc/Kconfig @@ -923,6 +923,7 @@ config STM32_ADC_CORE depends on ARCH_STM32 || COMPILE_TEST depends on OF depends on REGULATOR + depends on HAS_IOMEM select IIO_BUFFER select MFD_STM32_TIMERS select IIO_STM32_TIMER_TRIGGER
