From 4dab73d46eb58c142b5d2e7039f12e4e5df357ad Mon Sep 17 00:00:00 2001

Subject: [PATCH 196/224] mtd: mtk-nor: modify functions' name more generally
Since more and more Mediatek's SoC can use this driver to
control spi-nor flash, functions' name with "mt8173_" is
no longer properly. Replacing "mt8173_" with "mtk_" will
be more accurate to describe these functions' usable scope.
