Subject: [PATCH 1/6] soc: mediatek: mtk-svs: Commonize t-calibration-data fuse array read
Date:   Tue, 26 Jul 2022 16:16:48 +0200
Message-Id: <20220726141653.177948-2-angelogioacchino.delregno@collabora.com>

Precedence: bulk

Commonize the repeating pattern for reading the "t-calibration-data"
efuse data in a new function svs_thermal_efuse_get_data(), reducing
the size of this driver.

No functional changes.
