Hi Arnd,
I love your patch! Perhaps something to improve:
[auto build test WARNING on scsi/for-next]
[also build test WARNING on v4.15]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system]

The problem was resolved upon upgrading laptop-mode-tools to 1.72.2.
