commit: cd423dd3634a5232a3019eb372b144619a61cd16 From: Felipe Balbi <[email protected]> Date: Wed, 21 Mar 2012 11:44:00 +0200 Subject: 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.
