Subject: [PATCH V2 1/3] hwmon (coretemp): rearrange tjmax handing code
Date: Sun, 13 Nov 2022 23:31:43 +0800 [thread overview]
Message-ID: <20221113153145.32696-2-rui.zhang@intel.com> (raw)
In-Reply-To: <20221113153145.32696-1-rui.zhang@intel.com>
Rearrange the tjmax handling code so that it can be used directly in
the sysfs attribute callbacks without forward declarations.
No functional change in this patch.
