Re: [PATCH v2 3/7] iio: adc: qcom-spmi-rradc: introduce round robin adc

[kernel test robot <lkp@intel.com>]

Hi Caleb,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on robh/for-next]
[also build test ERROR on jic23-iio/togreg lee-mfd/for-mfd-next v5.16-rc8 next-20220105]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
https://git-scm.com/docs/git-format-patch]
