From: Wei Yongjun <weiyongjun1@huawei.com>

[ Upstream commit e2ae8bca494481a9f38fcd1d52943ac04e654745 ]

Fix to return negative error code from some error handling
cases instead of 0, as done elsewhere in this function.

Fixes: 091876cc355d ("phy: ti: j721e-wiz: Add support for WIZ module present in TI J721E SoC")
