Subject: [PATCH 5.12 148/173] phy: ti: Fix an error code in wiz_probe()

From: Yang Li <yang.lee@...ux.alibaba.com>

commit b8203ec7f58ae925e10fadd3d136073ae7503a6e upstream.

When the code execute this if statement, the value of ret is 0.
However, we can see from the dev_err() log that the value of
ret should be -EINVAL.

Clean up smatch warning:
