[PATCH -next] net: phy: Fix return value check in xgmiitorgmii_probe()

From: Wei Yongjun <redacted>
Date: Mon, 15 Aug 2016 22:34:57 +0000

In case of error, the function of_parse_phandle() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Applied.
