------------------

From: Salil <salil.mehta@xxxxxxxxxx>

commit b4957ab0826f6f7efdfdc648521e1c4c3fc6ceda upstream.

This patch fixes some checkpatch.pl script caught errors and
warnings during the compilation time.

[ backported to 4.9.y to fix build warnings caused by the backporting of
64ec10dc2ab8 ("net: hns: Correct HNS RSS key set function") by Sasha
