[PATCH] USB: net2280: send 0-length packets for ep0
This patch (as669) fixes a bug in the net2280 driver. Now it will properly send zero-length packets on ep0 until the control status stage occurs. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
