[PATCH 0/2] platform/chrome: check ACPI companions before use

[Jiale Yao]

Two Chrome platform drivers assume their firmware-matched devices always
carry an ACPI companion. Driver override can bind either driver to a device
without one, leading probe to dereference a NULL companion.

Reject missing companions before passing them to ACPI resource and notify
handler APIs. Each change is independent and preserves the normal
firmware-matched probe path.
