Subject: linux-next: build warning after merge of the staging tree

Hi all,

After merging the staging tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

drivers/iio/adc/stm32-adc-core.c: In function 'stm32_adc_core_switches_probe':
drivers/iio/adc/stm32-adc-core.c:598:5: warning: ignoring return value of 'dev_err_probe' declared with attribute 'warn_unused_result' [-Wunused-result]
  598 |     dev_err_probe(dev, ret, "can't get booster\n");
      |     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit

  ce30eeb613cb ("iio: adc: stm32: Simplify with dev_err_probe()")

Cheers,
Stephen Rothwell
