[PATCH] IIO: ADC: stm32-dfsdm: remove unused variable

[Arnd Bergmann]

A cleanup left one variable behind that is no longer needed and
can be removed, as shown by the gcc warning:

drivers/iio/adc/stm32-dfsdm-core.c: In function 'stm32_dfsdm_probe':
drivers/iio/adc/stm32-dfsdm-core.c:245:29: error: unused variable 'of_id' [-Werror=unused-variable]

Fixes: abaca806fd13 ("IIO: ADC: stm32-dfsdm: code optimization")
