Subject: [PATCH 4/8] thermal: rockchip: fix calculation error for code_to_temp
Date: Wed, 3 Feb 2016 12:12:43 +0800 [thread overview]
Message-ID: <1454472767-5767-5-git-send-email-wxt@rock-chips.com> (raw)
In-Reply-To: <1454472767-5767-1-git-send-email-wxt@rock-chips.com>
From: Elaine Zhang <zhangqing@rock-chips.com>
the calculation use a global table, not their own table.
so adapt the table to the correct one.
