Help needed to update MODDMA to for OS 6

Mbed OS
3

The updated MODDMA library worked fine with the following test program
when compiled for Mbed OS 6:

#include "mbed.h"
#include "MODDMA.h"

DigitalOut  myled(LED1);
DigitalOut  led2(LED2);
MODDMA      dma;
int         transferState = 0;

void myCallback(void)
{
    if (transferState == 0) {
        led2 = 1;
        transferState = 1;
    }
}

int main()
{
    printf("Hello World\r\n");

    // Create a source buffer we are going to move.
    char src[] = "TEST TEST TEST";

    // Create a buffer for the destination to copy to.
    char dst[sizeof(src)];

    // Create a MODDMA configuration object.
    MODDMA_Config*  config = new MODDMA_Config;

    // Setup that configuration

    config
        ->channelNum(MODDMA::Channel_0)
        ->srcMemAddr((uint32_t) & src)
        ->dstMemAddr((uint32_t) & dst)
        ->transferSize(sizeof(src))
        ->transferType(MODDMA::m2m)
        ->attach_tc(&myCallback);
    // config end

    // Pass the configuration to the controller
    dma.Setup(config);

    // Tell the controller to perform the DMA operation
    // defined by that configuration.
    dma.Enable(config);

    while (1) {
        if (transferState == 1) {
            transferState = 2;
            printf("%s\r\n", dst);
        }

        myled = 1;
        ThisThread::sleep_for(250ms);
        myled = 0;
        ThisThread::sleep_for(250ms);
    }
}
