Hi Stefan,

I love your patch! Yet something to improve:

[also build test ERROR on slave-dma/next v5.5-rc7]
[cannot apply to mripard/sunxi/for-next next-20200120]
[if your patch is applied to the wrong git tree, please drop us a note to help

base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
