Subject: [PATCH 0/2] Fix kernel panic in scsi_queue_rq()

'cfee29ffb45b ("scsi: core: Do not increase scsi_device's iorequest_cnt
if dispatch failed")' introduce bug which would cause kernel panic.

So revert the changes and fix the origin issue by decreasing the
iorequest_cnt if scsi_dispatch_cmd return failed.

Wenchao Hao (2):
  Revert "scsi: core: Do not increase scsi_device's iorequest_cnt if
    dispatch failed"
  scsi: core: decrease scsi_device's iorequest_cnt if dispatch failed
