Subject: [PATCH v4 11/14] soc: mediatek: mtk-svs: delete superfluous platform data entries
Date:   Wed, 11 Jan 2023 15:45:25 +0800
Message-ID: <20230111074528.29354-12-roger.lu@mediatek.com>

From: Matthias Brugger <matthias.bgg@gmail.com>

The platform name and efuse parsing function pointer are only used while
probing the device. Use them from the svs_platform_data struct instead.
