Hi Enric,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on ljones-mfd/for-mfd-next]
[also build test ERROR on robh/for-next linus/master v5.6-rc4 next-20200305]
[cannot apply to linux/master]
[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]
