Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel before 5.17, drivers/phy/tegra/xusb.c mishandles the tegra_xusb_find_port_node return value. Callers expect NULL in the error case, but an error pointer is used.
