Subject: [PATCH v4 07/22] hw/acpi/ich9: Remove dead code related to 'acpi_memory_hotplug'
Date: Tue, 16 Apr 2024 20:59:23 +0200 [thread overview]
Message-ID: <20240416185939.37984-8-philmd@linaro.org> (raw)
In-Reply-To: <20240416185939.37984-1-philmd@linaro.org>
acpi_memory_hotplug::is_enabled is set to %true once via
ich9_lpc_initfn() -> ich9_pm_add_properties(). No need to
check it, so remove now dead code.
