3.16.7-ckt10 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Thierry Reding <treding@xxxxxxxxxx>
commit 2f1bce487cd0a02623cff3d877940f9a2026341c upstream.
devm_phy_create() stores the pointer to the new PHY at the address
returned by devres_alloc(). The res parameter passed to devm_phy_match()
is therefore the location where the pointer to the PHY is stored, hence
it needs to be dereferenced before comparing to the match data in order
to find the correct match.
