-Subject: net: dsa: mt7530: fix null pointer dereferencing in port5 setup
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-The 2nd gmac of mediatek soc ethernet may not be connected to a PHY
-and a phy-handle isn't always available.
-Unfortunately, mt7530 dsa driver assumes that the 2nd gmac is always
-connected to switch port 5 and setup mt7530 according to phy address
-of 2nd gmac node, causing null pointer dereferencing when phy-handle
-isn't defined in dts.
-This commit fix this setup code by checking return value of
-of_parse_phandle before using it.
