[PATCH] phy: rockchip-dp: fix return value check in rockchip_dp_phy_probe()

[weiyj_lk]

From: Wei Yongjun <yongjun_...@trendmicro.com.cn>

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