Subject: usb: dwc3: ep0: increment "actual" on bounced ep0 case
From: Felipe Balbi <[email protected]>
commit cd423dd3634a5232a3019eb372b144619a61cd16 upstream.
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.
