 * acpi_set_modalias - Set modalias using "compatible" property or supplied ID

 * @default_id:	ID string to use as default if no compatible string found

 * @modalias:   Pointer to buffer that modalias value will be copied into

 * @len:	Length of modalias buffer

 *

 * This is a counterpart of of_modalias_node() for struct acpi_device objects.

 * If there is a compatible string for @adev, it will be copied to @modalias

 * with the vendor prefix stripped; otherwise, @default_id will be used.
