Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull late SCSI updates from James Bottomley:
 "This is mostly stuff which missed the initial pull.

  There's a new driver: qedi, and some ufs, ibmvscsis and ncr5380
  updates plus some assorted driver fixes and also a fix for the bug
  where if a device goes into a blocked state between configuration and
  sysfs device add (which can be a long time under async probing) it
  would become permanently blocked"

 This file documents the NCR53c400 extensions by Kevin Lentin and some
 enhancements to the NCR5380 core.
 
-This driver supports both NCR5380 and NCR53c400 cards in port or memory
-mapped modes. Currently this driver can only support one of those mapping
-modes at a time but it does support both of these chips at the same time.
-The next release of this driver will support port & memory mapped cards at
-the same time. It should be able to handle multiple different cards in the
-same machine.
+This driver supports NCR5380 and NCR53c400 and compatible cards in port or
+memory mapped modes.
 
-The drivers/scsi/Makefile has an override in it for the most common
-NCR53c400 card, the Trantor T130B in its default configuration:
-	Port: 0x350
-	IRQ : 5
+Use of an interrupt is recommended, if supported by the board, as this will
+allow targets to disconnect and thereby improve SCSI bus utilization.
+
+If the irq parameter is 254 or is omitted entirely, the driver will probe
+for the correct IRQ line automatically. If the irq parameter is 0 or 255
+then no IRQ will be used.
 
 The NCR53c400 does not support DMA but it does have Pseudo-DMA which is
 supported by the driver.
