Tested the new armhf kernel on RPi3B+; copied 40Mb and 600Mb files
successfully with no issues. Compared performance of the 40Mb copy+sync
to the same machine running Disco (which has dwc_otg) and performance on
eoan with the new kernel was marginally quicker (6.8-7.0s on eoan with
dwc2 vs 8.2s-8.5s on disco with dwc_otg). I'd guess that that's down to
kernel improvements generally between disco and eoan rather than
anything to do with the driver, but at least it demonstrates there's no
performance regression.

Looking good overall!
