SCSI misc on 20161014 

This is just a set of minor updates and fixes which weren't quite ready in
 time for the first pull request.  The only real thing of note is Mike Christie
 is stepping down as Maintainer of iscsi to be replaced by Lee Duncan and Chris
 Leech.

@ -21,16 +21,6 @@ NCR53c400 card, the Trantor T130B in its default configuration:
The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
supported by the driver.
If the default configuration does not work for you, you can use the kernel
command lines (eg using the lilo append command):
ncr5380=addr,irq
ncr53c400=addr,irq
ncr53c400a=addr,irq
dtc3181e=addr,irq
The driver does not probe for any addresses or ports other than those in
the OVERRIDE or given to the kernel as above.
This driver provides some information on what it has detected in
/proc/scsi/g_NCR5380/x where x is the scsi card number as detected at boot
time. More info to come in the future.
