[PATCH -next] spi: fix return value check in ce4100_spi_probe()

[Wei Yongjun]

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

In case of error, the function platform_device_register_full()
returns ERR_PTR() and never returns NULL. The NULL test in the
return value check should be replaced with IS_ERR().
