ACPI: processor: idle: Clean up max_cstate update logic

[PATCH v2 0/3] ACPI: processor: idle: Clean up max_cstate update logic

Posted by Huisong Li 3 weeks, 6 days ago

The acpi_processor_cstate_first_run_checks() just need to call once
in acpi_processor_register_idle_driver().  This series cleans up the
redundant calls and internal guards.

---
Changes in v2:
- Add a new patch which move max_cstate update out of the loop in
  acpi_processor_register_idle_driver.

---
Huisong Li (3):
  ACPI: processor: idle: Remove redundant cstate check in acpi_processor_power_init
  ACPI: processor: idle: Move max_cstate update out of the loop
  ACPI: processor: idle: Remove redundant static variable and rename cstate check function
