This patch fixes one bugs of OUT transfer in double buffer case: -the current code only enable autoclear for dma mode 1, and not for dma mode 0 Without this patch, test #5 of usbtest can't be passed if we configure musb as g_zero and use fifo mode 3 to enable double buffer mode. With this patch and the following patch(fix dma length), on my beagle B5, test#5(queued bulk out) may go beyond 18Mbyte/s(seems dma mode 0 is quicker in double buffer case) if musb is configured as g_zero and fifo mode 3 is taken, follows the test command: #./testusb -D DEV_NAME -c 1024 -t 5 -s 32768 -g 8 [1] Also I have tested this patch can't make g_ether broken.
