With some SDIO devices, timeout errors can happen when reading data. To solve
this issue the DMA transfer has to be activated before sending the command to
the device. This order is incorrect in PDC mode. So we have to take care if we
are using DMA or PDC to know when to s

In some cases, a NULL pointer dereference happens because data is NULL when

When a software timeout occurs, the transfer is not stopped. In DMA case, it
causes DMA channel to be stuck because the transfer is still active causing
following transfers to be queued but not computed.
