usb: musb: cppi41: fix not transmitting zero length packet issue CPPI TX does not transmit ZLP for TX transfers which - transfer size is multiple of EP packet size, - and URB_ZERO_PACKET is set in urb->transfer_flags. The fix is transmitting the ZLP using PIO mode after the CPPI TX is done. Validated using the following usbtest write case in MUSB host mode. # testusb -t1 -c1 Signed-off-by: Bin Liu <b-liu@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
