Subject: [PATCH v1] cpufreq: ACPI: Use on_each_cpu_mask() in drv_write()
Date: Tue, 09 Sep 2025 13:41:30 +0200 [thread overview]
Message-ID: <2797300.mvXUDI8C0e@rafael.j.wysocki> (raw)
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Make drv_write() call on_each_cpu_mask() instead of using an open-coded
equivalent of the latter.
No intentional functional impact.
