Merge branch 'scsi-target-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/bvanassche/linux

Pull SCSI target fixes from Bart Van Assche:

 - two small fixes for the ibmvscsis driver

 - ten patches with bug fixes for the target mode of the qla2xxx driver

 - four patches that avoid that the "sparse" and "smatch" static
   analyzer tools report false positives for the qla2xxx code base

* 'scsi-target-for-v4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/bvanassche/linux:
  qla2xxx: Disable out-of-order processing by default in firmware
  qla2xxx: Fix erroneous invalid handle message
  qla2xxx: Reduce exess wait during chip reset
  qla2xxx: Terminate exchange if corrupted
  qla2xxx: Fix crash due to null pointer access
  qla2xxx: Collect additional information to debug fw dump
  qla2xxx: Reset reserved field in firmware options to 0
  qla2xxx: Set tcm_qla2xxx version to automatically track qla2xxx version
  qla2xxx: Include ATIO queue in firmware dump when in target mode
  qla2xxx: Fix wrong IOCB type assumption
  qla2xxx: Avoid that building with W=1 triggers complaints about set-but-not-used variables
  qla2xxx: Move two arrays from header files to .c files
  qla2xxx: Declare an array with file scope static
  qla2xxx: Fix indentation
  ibmvscsis: Fix sleeping in interrupt context
  ibmvscsis: Fix max transfer length
