Hi Hans,

I love your patch! Yet something to improve:

[auto build test ERROR on linus/master]
[also build test ERROR on v6.2-rc5]
[cannot apply to media-tree/master]
[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
