Hi Benjamin,
I love your patch! Perhaps something to improve:
[auto build test WARNING on balbi-usb/next]
[also build test WARNING on v4.15-rc9 next-20180119]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
This seems to be bogosity in m32r more than problems with the driver...

Not sure what that one is, looks like some toolchain or arch problem...

This is rather bogus too. m32r's readl() is returning unsigned long, it
should be unsigned int or u32.
Unfortunately m32r is marked orphaned in MAINTAINERS. We could stop
testing it if no one will step up to fix its issues.
Thanks,
