Linus Torvalds 959bfe496b ACPI support updates for 6.19-rc1
- Avoid walking the ACPI namespace in the AML interpreter if the
    starting node cannot be determined (Cryolitia PukNgae)
 
  - Use min() instead of min_t() in the ACPI device properties handling
    code to avoid discarding significant bits (David Laight)
 
  - Fix potential fwnode refcount leak in acpi_fwnode_graph_parse_endpoint()
    that may prevent the parent fwnode from being released (Haotian Zhang)
 
  - Rework acpi_graph_get_next_endpoint() to use ACPI functions only, remove
    unnecessary conditionals from it to make it easier to follow, and make
    acpi_get_next_subnode() static (Sakari Ailus)
 
  - Drop unused function acpi_get_lps0_constraint(), make some Low-Power
    S0 callback functions for suspend-to-idle static, and rearrange the
    code retrieving Low-Power S0 constraints so it only runs when the
    constraints are actually used (Rafael Wysocki)
 
  - Drop redundant locking from the ACPI battery driver (Rafael Wysocki)
 
  - Improve runtime PM in the ACPI time and alarm device (TAD) driver
    using guard macros and rearrange code related to runtime PM in
    acpi_tad_remove() (Rafael Wysocki)
 
  - Add support for Microsoft fan extensions to the ACPI fan driver along
    with notification support and work around a 64-bit firmware bug in
    that driver (Armin Wolf)
 
  - Use ACPI_FREE() to free ACPI buffer in the ACPI DPTF code (Kaushlendra
    Kumar)
 
  - Fix a memory leak and a resource leak in the ACPI pfrut utility (Malaya
    Kumar Rout)
 
  - Replace `core::mem::zeroed` with `pin_init::zeroed` in the ACPI Rust
    code (Siyuan Huang)
 
  - Update the ACPI code to use the new style of allocating workqueues
    and new global workqueues (Marco Crivellari)
 
  - Fix two spelling mistakes in the ACPI code (Chu Guangqing)
 
  - Fix ISAPNP to generate uevents to auto-load modules (René Rebe)
 
  - Relocate the state flags initialization in the ACPI processor idle
    driver and drop redundant C-state count checks from it (Huisong Li)
 
  - Fix map_x2apic_id() in the ACPI processor core driver for amd-pstate
    on am4 (René Rebe)

Pull ACPI updates from Rafael Wysocki:
 "These add Microsoft fan extensions support to the ACPI fan driver, fix
  a bug in ACPICA, update other ACPI drivers (processor, time and alarm
  device), update ACPI power management code and ACPI device properties
  management, and fix an ACPI utility:
