Subject: [PATCH V3 2/4] thermal/drivers/hisi: Add platform prefix to function name
From: Kevin Wangtao <kevin.wangtao@...aro.org>
As the next patches will provide support for the hikey3660's sensor,
several functions with the same purpose but for different platforms will
be introduced.
In order to make a clear distinction between them, let's prefix the
function names with the platform name.
This patch has no functional changes, only name changes.
