Varible type lead to error action in xspi.c

[ZoroGH]

I discover that the var RemainingBytes is unsigned int，so if my tansfer data bytes is not the times of DataWidth , it will fill the fifo untill it's full.

so, i think here the while loop should be :

    while (((StatusReg & XSP_SR_TX_FULL_MASK) == 0) &&
        (InstancePtr->RemainingBytes > 0)) {
        if (DataWidth == XSP_DATAWIDTH_BYTE) {
            /*
             * Data Transfer Width is Byte (8 bit).
             */
            Data = *InstancePtr->SendBufferPtr;
        } else if (DataWidth == XSP_DATAWIDTH_HALF_WORD) {
            /*
             * Data Transfer Width is Half Word (16 bit).
             */
            Data = *(u16 *)InstancePtr->SendBufferPtr;
        } else if (DataWidth == XSP_DATAWIDTH_WORD){
            /*
             * Data Transfer Width is Word (32 bit).
             */
            Data = *(u32 *)InstancePtr->SendBufferPtr;
        }

        XSpi_WriteReg(InstancePtr->BaseAddr, XSP_DTR_OFFSET, Data);
        InstancePtr->SendBufferPtr += (DataWidth >> 3);
//********************************************************************
        if(InstancePtr->RemainingBytes <(DataWidth >> 3))
        {
            StatusReg = XSpi_GetStatusReg(InstancePtr);
            break;
        }
//********************************************************************
        InstancePtr->RemainingBytes -= (DataWidth >> 3);
        StatusReg = XSpi_GetStatusReg(InstancePtr);
    }
