Merge branches 'acpi-properties', 'acpi-tables', 'acpi-x86' and 'acpi-soc'
Merge changes related to ACPI data-only tables handling and ACPI device properties management, x86-specific ACPI code changes and ACPI SoC driver changes for 6.1-rc1: - Clean up the ACPI LPSS (Intel SoC) driver (Andy Shevchenko). - Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable (Mario Limonciello). - Drop unused dev_fmt() and redundant 'HMAT' prefix from the HMAT parsing code (Liu Shixin). - Make ACPI FPDT parsing code avoid calling acpi_os_map_memory() on invalid physical addresses (Hans de Goede). - Silence missing-declarations warning related to Apple device properties management (Lukas Wunner). * acpi-properties: ACPI: property: Silence missing-declarations warning in apple.c * acpi-tables: ACPI: HMAT: Drop unused dev_fmt() and redundant 'HMAT' prefix ACPI: tables: FPDT: Don't call acpi_os_map_memory() on invalid phys address * acpi-x86: ACPI: x86: Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable * acpi-soc: ACPI: LPSS: Deduplicate skipping device in acpi_lpss_create_device() ACPI: LPSS: Replace loop with first entry retrieval
