The\ndereference was introduced when the probe function was switched from\nACPI_HANDLE() to ACPI_COMPANION().\n\nCheck the ACPI companion against NULL and return -ENODEV when it is\nmissing, like commit e4865a56d013 (\"ACPI: driver: Check ACPI_COMPANION()\nagainst NULL during probe\") does for the core ACPI platform drivers."
