Subject: [PATCH v0 4/6] ACPI: TAD: Clear unused RT data in acpi_tad_set_real_time()
Date: Sun, 22 Feb 2026 15:17:47 +0100	[thread overview]
Message-ID: <3416235.44csPzL39Z@rafael.j.wysocki> (raw)
In-Reply-To: <4727679.LvFx2qVVIh@rafael.j.wysocki>

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Move the clearing of the fields in struct acpi_tad_rt that are not used
on the real time setting side to acpi_tad_set_real_time().

No intentional functional impact.
