Subject: Re: [PATCH v2 3/3] iio: cros_ec_light: Add support for RGB sensor
Hi Gwendal,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on iio/togreg]
[also build test WARNING on chrome-platform-linux/for-next linus/master v5.7-rc5 next-20200508]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
