[DPDK/other Bug 1871] idxd_dmadev.portal volatile usage

            Bug ID: 1871
           Summary: idxd_dmadev.portal volatile usage
           Product: DPDK
           Version: 21.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other
          Assignee: dev@dpdk.org
          Reporter: scott.k.mitch1@gmail.com
  Target Milestone: ---

idxd_dmadev_probe_pci uses RTE_PTR_ADD(idxd.u.pci->portals) [1] where the
argument is volatile [2] and assigns the result to idxd_dmadev.portal which is
not volatile [3]. Disqualifying quantifiers should be done explicitly if
desired (not implicitly through RTE_PTR_ADD) and clear comments added, or
qualifiers should be preserved.
