Subject: [PATCH] thermal/drivers/mediatek/lvts_thermal: Remove redundant code in lvts_ctrl_configure
Date: Wed, 10 Apr 2024 08:07:28 +0800
Message-ID: <20240410000730.628043-1-treapking@chromium.org>

The removed variable assignment is never written to the register, so it
has no effect on the device behavior.  Mediatek has confirmed that it
is not required to initialize this register for current platforms, so
remove this segment to avoid confusion.
