Merge branch 'acpi-scan'
Merge ACPI device enumeration fixes for 6.10-rc5: - Ignore MIPI camera graph port nodes created with the help of the information from the ACPI tables on all Dell Tiger, Alder and Raptor Lake models as that information is reported to be invalid on the systems in question (Hans de Goede). - Use new Intel CPU model matching macros in the MIPI DisCo for Imaging part of ACPI device enumeration (Hans de Goede). * acpi-scan: ACPI: mipi-disco-img: Switch to new Intel CPU model defines ACPI: scan: Ignore camera graph port nodes on all Dell Tiger, Alder and Raptor Lake models
