Subject: [GIT PULL] SCSI fixes for 4.12-rc6

Two fixes to remove spurious WARN_ONs from the new(ish) qedi driver. 
 The driver already prints a warning message, there's no need to panic
users by printing something that looks like an oops as well.

The patch is available here:

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes

The short changelog is:

Manish Rangankar (2):
      scsi: qedi: Remove WARN_ON from clear task context.
      scsi: qedi: Remove WARN_ON for untracked cleanup.
