This will add the CRC calculation according
to the CRC ITU-T V.41 to the kernel lib/ folder.

This code has been derived from the rt2x00 driver,
currently found only in the wireless-dev tree, but
this library is generic and could be used by more
drivers who currently use their own implementation.

In some situations we can receive the ORB status write before we
have received the ORB pointer write response.  When this happens,
we assume that the fw_transaction is finished and free the ORB
struct containing the fw_transaction.

This fix make the status write logic only accept status writes
for ORBs where the initial ORB pointer write transaction finished.

Some devices have a really long power-on cycle, and we fail to

There's really no down-side to bumping the number of retries and the

of retries anyway.

In case the topology build fails, we want to retain the old topology

we clear card->irm_node to NULL and the topology build fails, we end up
dereferencing a NULL pointer in a few places.
