drm/hisilicon: Fix return value check in ade_dts_parse()
In case of error, the function devm_clk_get() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Reviewed-by: Chen Feng <puck.chen@hisilicon.com>
