SCSI misc on 20210219 

This series consists of the usual driver updates (ufs, ibmvfc,
 qla2xxx, hisi_sas, pm80xx) plus the removal of the gdth driver (which
 is bound to cause conflicts with a trivial change somewhere).  The
 only big major rework of note is the one from Hannes trying to clean
 up our result handling code in the drivers to make it consistent.

@ -1161,3 +1161,14 @@ Description: This entry shows the configured size of WriteBooster buffer.
0400h corresponds to 4GB.
The file is read only.
What: /sys/bus/platform/drivers/ufshcd/*/wb_on
Date: January 2021
Contact: Bean Huo <beanhuo@micron.com>
Description: This node is used to set or display whether UFS WriteBooster is
enabled. Echo 0 to this file to disable UFS WriteBooster or 1 to
enable it. The WriteBooster is enabled after power-on/reset,
however, it will be disabled/enable while CLK scaling down/up
(if the platform supports UFSHCD_CAP_CLK_SCALING). For a
platform that doesn't support UFSHCD_CAP_CLK_SCALING, we can
disable/enable WriteBooster through this sysfs node.
