Subject: usb: dwc3: ep0: increment "actual" on bounced ep0 case
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=cd423dd3634a5232a3019eb372b144619a61cd16;p=deliverable%2Flinux.git

usb: dwc3: ep0: increment "actual" on bounced ep0 case

due to a HW limitation we have a bounce buffer for ep0
out transfers which are not aligned with MaxPacketSize.

On such case we were not increment r->actual as we should.

This patch fixes that mistake.
