Merge patch series "smartpqi updates"

Don Brace <[email protected]> says:

These patches are based on Martin Petersen's 6.4/scsi-queue tree
  https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
  6.4/scsi-queue

This set of changes consists of:

 * Map entire BAR 0.  The driver was mapping up to and including the
   controller registers, but not all of BAR 0.

 * Add PCI IDs to support new controllers.

 * Clean up some code by removing unnecessary NULL checks.  This cleanup is
   a result of a Coverity report.

 * Correct a rare memory leak whenever pqi_sas_port_add_rhpy() returns an
   error. This was Suggested by: Yang Yingliang <[email protected]>

 * Remove atomic operations on variable raid_bypass_cnt. Accuracy is not
   required for driver operation. Change type from atomic_t to unsigned
   int.

 * Correct a rare drive hot-plug removal issue where we get a NULL
   io_request. We added a check for this condition.

 * Turn on NCQ priority for AIO requests to disks comprising RAID devices.

 * Correct byte aligned writew() operations on some ARM servers. Changed
   the writew() to two writeb() operations.

 * Change how the driver checks for a sanitize operation in progress.  We
   were using TEST UNIT READY. We removed the TEST UNIT READY code and are
   now using the controller's firmware information in order to avoid issues
   caused by drives failing to complete TEST UNIT READY.

 * Some customers have been requesting that we add the NUMA node to
   /sys/block/sd<scsi device>/device like the nvme driver does.

 * Update the copyright information to match the current year.

 * Bump the driver version to 2.1.22-040.
