Storing CRC-32 hash of the Physical Location of Device object (_PLD) with devices that have it. The hash is stored to a new struct acpi_device member "pld_crc". The hash makes it easier to find devices that share a location, as there is no need to evaluate the entire object every time. Knowledge about devices that share a location can be used in device drivers that need to know the connections to other components inside a system. USB3 ports will for example always share their location with a USB2 port. Acked-by: Rafael J.
