smatch reports several warnings
drivers/iio/adc/stm32-adc.c:2591:20: warning:
symbol 'stm32_adc_min_ts_h7' was not declared. Should it be static?
drivers/iio/adc/stm32-adc.c:2610:20: warning:
symbol 'stm32_adc_min_ts_mp1' was not declared. Should it be static?
drivers/iio/adc/stm32-adc.c:2630:20: warning:
symbol 'stm32_adc_min_ts_mp13' was not declared. Should it be static?
These variables are only used in stm32-adc.c, so they should be static

Thanks Tom,
I wonder why these didn't show up in earlier build reports?
Ah well.
Applied to the togreg branch of iio.git and pushed out as testing for
0-day to take a look at it.
Thanks,
