i2c-mux ACPI parent device references in example

[Jonas Gorski <jonas.gorski@gmail.com>]

Hi,

I'm currently trying to wrap my head around describing devices via SSDT.

While reading Documentation/firmware-guide/acpi/i2c-muxes.rst, the
references used for the devices behind the mux confuse me a bit.

The tree from the example is:

    Device (SMB1)
    {
        Device (MUX0)
        {
            Device (CH00)
            {
                Device (CLIA)
                {
                    Name (_CRS, ResourceTemplate () {
                        I2cSerialBus (0x50, ControllerInitiated, I2C_SPEED,
                                    AddressingMode7Bit, "\\_SB.SMB1.CH00", 0x00,
                                    ResourceConsumer,,)
                    }
                }
            }

            Device (CH01)
            {
                Device (CLIB)
                {
                    Name (_CRS, ResourceTemplate () {
                        I2cSerialBus (0x50, ControllerInitiated, I2C_SPEED,
                                    AddressingMode7Bit, "\\_SB.SMB1.CH01", 0x00,
                                    ResourceConsumer,,)
                    }
                }
            }
        }
    }


Is there a ".MUX0" missing in the references, or is it correct that it is not
present?

E.g. should it be "\\_SB.SMB1.MUX0.CH00" instead of "\\_SB.SMB1.CH00"?

FWIW, the references were changed from relative to absolute in e65cb011349e
("Documentation: ACPI: Fix parent device references").
