[SRU][Zesty][PATCH 0/1] powerpc/npu-dma: Remove spurious WARN_ON when a PCI device has no of_node

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1702768

== SRU Justification ==
A stack trace is generated when enabling SRIOV on power.  This bug was introduced
by commit 4c3b89effc28 in v4.12-rc1.  However, the bug made its way into Zesty
via bug 1690412.  This bug is fixed by mainline commit 377aa6b0efba, which was added
in v4.12-rc6. 


== Fix ==
commit 377aa6b0efbaa29cfeecd8b9244641217f9544ca

    powerpc/npu-dma: Remove spurious WARN_ON when a PCI device has no of_node


== Regression Potential ==
This fix is specific to power, so low risk for regression.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
