Prashant Malani 16960ac92b platform/chrome: cros_ec_typec: Check for EC device ... commit ffebd90532 upstream. The Type C ACPI device on older Chromebooks is not generated correctly (since their EC firmware doesn't support the new commands required). In such cases, the crafted ACPI device doesn't have an EC parent, and it is therefore not useful (it shouldn't be generated in the first place since the EC firmware doesn't support any of the Type C commands). To handle devices which use these older firmware revisions, check for the parent EC device handle, and fail the probe if it's not found.
