Message-ID: <20260129041433.3458902-2-lihuisong@huawei.com> Date: Thu, 29 Jan 2026 12:14:32 +0800 From: Huisong Li <lihuisong@...wei.com> To: <rafael@...nel.org>, <lenb@...nel.org>, <bp@...en8.de> CC: <linux-acpi@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <linuxarm@...wei.com>, <jonathan.cameron@...wei.com>, <zhanjie9@...ilicon.com>, <zhenglifeng1@...wei.com>, <yubowen8@...wei.com>, <zhangpengjie2@...wei.com>, <wangzhi12@...wei.com>, <lihuisong@...wei.com> Subject: [PATCH 1/2] ACPI: processor: Remove redundant cstate check in power init The function acpi_processor_cstate_first_run_checks() is responsible for updating max_cstate and performing initial hardware validation. Currently, this function is invoked within acpi_processor_power_init(). However, the initialization flow already ensures this is called during acpi_processor_register_idle_driver(). Therefore, the call in acpi_processor_power_init() is redundant and effectively performs no work.
