[PATCH v2] PCI: dra7xx: Added error handling in probe function when devm_phy_get() fails

From: Riyan Dhiman
Date: Tue Oct 01 2024 - 06:58:02 EST


While creation of device link, if devm_phy_get() function fails then it
directly returns PTR_ERR without any cleanup of previous added device
links.

Added goto statement to handle the cleanup of already added device links.

Fixes: 7a4db656a635 (PCI: dra7xx: Create functional dependency between
PCIe and PHY)
