usb: dwc2: Fix INTR OUT transfers in DDMA mode.
In DDMA mode if INTR OUT transfers mps not multiple of 4 then single packet corresponds to single descriptor. Descriptor limit set to mps and desc chain limit set to mps * MAX_DMA_DESC_NUM_GENERIC. On that descriptors complete, to calculate transfer size should be considered correction value for each descriptor. In start request function, if "continue" is true then dma buffer address should be incremmented by offset for all type of transfers, not only for Control DATA_OUT transfers. Fixes: cf77b5fb9b394 ("usb: dwc2: gadget: Transfer length limit checking for DDMA") Fixes: e02f9aa6119e0 ("usb: dwc2: gadget: EP 0 specific DDMA programming") Fixes: aa3e8bc81311e ("usb: dwc2: gadget: DDMA transfer start and complete") Signed-off-by: Minas Harutyunyan <hminas@synopsys.com> Signed-off-by: Felipe Balbi <balbi@kernel.org>
