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.
