Hi Nicholas,
I love your patch! Yet something to improve:
[auto build test ERROR on openrisc/for-next]
[also build test ERROR on sparc-next/master sparc/master linus/master asm-generic/master xtensa/for_next v5.8-rc7 next-20200728]
[cannot apply to nios2/for-linus]
[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
https://git-scm.com/docs/git-format-patch]
