Subject: [PATCH] phy: tegra: xusb: Fix return value of tegra_xusb_find_port_node function

Git-commit: 045a31b95509c8f25f5f04ec5e0dec5cd09f2c5f

Patch-mainline: v5.17-rc1

References: CVE-2023-23000 bsc#1208816

callers of tegra_xusb_find_port_node() function only do NULL checking for

the return value. return NULL instead of ERR_PTR(-ENOMEM) to keep

consistent.
