In the Linux kernel, the following vulnerability has been resolved:

tpm_crb: Check ACPI_COMPANION() against NULL during probe

Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.

Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
tpm_crb driver.
