Subject: [PATCH 5.9 020/252] net: ethernet: ti: cpsw: fix error return code in cpsw_probe()

From: Zhang Changzhong <zhangchangzhong@...wei.com>

[ Upstream commit 35f735c665114840dcd3142f41148d07870f51f7 ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.
