Subject: net: phy: Fix return value check in xgmiitorgmii_probe()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=64721094b9a966c8e02d2b03729e5093471f9d1c;p=openwrt%2Fstaging%2Fblogic.git

net: phy: Fix return value check in xgmiitorgmii_probe()

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.
