Fabrice Gasnier 20c89b4d1d iio: trigger: stm32-timer: fix build issue when disabled ... This fixes a build issue when CONFIG_IIO_STM32_TIMER_TRIGGER isn't set but used in stm32-dfsdm-adc driver (e.g. CONFIG_STM32_DFSDM_ADC is set): ERROR: "is_stm32_timer_trigger" [drivers/iio/adc/stm32-dfsdm-adc.ko] undefined! There are two possible options to fix this issue: - select IIO_STM32_TIMER_TRIGGER along with CONFIG_STM32_DFSDM_ADC. This is what's being done currently for CONFIG_STM32_ADC. - stub "is_stm32_timer_trigger" function Choice is made to stub this function as suggested in [1]. This is also inspired by similar "is_stm32_lptim_trigger" function (see [2]) in include/linux/iio/timer/stm32-lptim-trigger.h [1] https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg1977377.html [2] https://lkml.org/lkml/2017/9/10/124 Fixes: 11646e81d7 ("iio: adc: stm32-dfsdm: add support for buffer modes") Reported-by: Randy Dunlap <rdunlap@infradead.org> Fix-suggested-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>		2019-04-22 11:34:14 +01:00
