+Subject: net: cavium: liquidio: fix up "Avoid dma_unmap_single on uninitialized ndata"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This fixes up commit 1d1cb762524f05cfb37994e0d36b7b4b5e957134 which was
+commit 8e6ce7ebeb34f0992f56de078c3744fb383657fa upstream.
+
+Ben writes:
+ This goto should not have been changed, as no DMA mapping has been
+ attempted at this point in the function.
+
+ This seems to have been fixed upstream by commit 6a885b60dad2 "liquidio:
+ Introduce new octeon2/3 header". I leave it to you to work out how it
+ should be fixed in 4.4-stable.
+
+Fix this up by hand, as the referenced patch isn't worthy of being
+backported.
