Hi Catalin,
I love your patch! Yet something to improve:
[auto build test ERROR on arm-soc/for-next]
[also build test ERROR on arm/for-next linus/master v5.6-rc3 next-20200226]
[cannot apply to arm64/for-next/core kvmarm/next xlnx/master arm-perf/for-next/perf]
[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]
