[0/7] NCR5380 drivers: fixes and improvements

Message

Among other improvements, this patch series fixes a data corruption bug
in the mac_scsi driver and a bug in the EH abort routine in the core
5380 driver.

For consistency I have ignored certain checkpatch.pl complaints about
the indentation in mac_scsi.c. The remaining complaints seem to be
false positives.

Some of these patches are not trivial to backport. Those patches have
been nominated for recent -stable branches only.
