Subject: [PATCH v4 22/22] hw/i386/pc: Replace PCMachineClass::acpi_data_size by PC_ACPI_DATA_SIZE
Date: Tue, 16 Apr 2024 20:59:38 +0200	[thread overview]
Message-ID: <20240416185939.37984-23-philmd@linaro.org> (raw)
In-Reply-To: <20240416185939.37984-1-philmd@linaro.org>

PCMachineClass::acpi_data_size was only used by the pc-i440fx-2.0
machine, which got removed. Since it is constant, replace the class
field by a definition (local to hw/i386/pc.c, since not used
elsewhere).
