Hi Niklas,
I love your patch! Yet something to improve:
[auto build test ERROR on soc/for-next]
[also build test ERROR on asm-generic/master v5.12-rc8 next-20210421]
[cannot apply to arc/for-next sparc-next/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
