Done with a prefix of 'REPOST' to hopefully make it obvious nothing
changed between the RFT and this version.  There were only two
test-by, but as mentioned in the updated cover letter:

Since there should be nothing platform specific about the uFrame
scheduler presumably this should mean we're good to go?  Specificaly
note that in at least one of the "Tested-by" reports this patch caused
a notable improvement.


BTW: I'm pleased to have you apply the patches, but I notice that
get_maintainer no longer flags you as the person to post dwc2 patches
to.  From linux-next:

$ ./scripts/get_maintainer.pl -f drivers/usb/dwc2
