Subject: [PATCH] thermal: imx_sc_thermal: Fix incorrect data type
Date: Thu, 19 Mar 2020 16:26:20 +0800	[thread overview]
Message-ID: <1584606380-9972-1-git-send-email-Anson.Huang@nxp.com> (raw)

The temperature value passed from SCU could be negative value,
the data type should be signed instead of unsigned.

Fixes: ed0843633fee ("thermal: imx_sc: add i.MX system controller thermal support")
