Hi Mark, Thank you for the patch! Yet something to improve: [auto build test ERROR on asm-generic/master] [also build test ERROR on kvmarm/next linus/master v5.5-rc7] [cannot apply to arm64/for-next/core arm-perf/for-next/perf next-20200124] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system.
