Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: Fix NULL pointer dereference in tcpm_pd_svdm()
It is possible that typec_register_partner() returns ERR_PTR on failure. When port->partner is an error, a NULL pointer dereference may occur as shown below.

Add a check for port->partner to avoid dereferencing a NULL pointer.
