[PATCH] ASoC: fsl_spdif: fix return value check in fsl_spdif_probe()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

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