Subject: [PATCH 17/19] hwmon/coretemp: Cosmetic: Rename internal variables to zones from packages
Date: Mon, 13 May 2019 13:59:01 -0400	[thread overview]
Message-ID: <facecfd3525d55c2051f63a7ec709aeb03cc1dc1.1557769318.git.len.brown@intel.com> (raw)
In-Reply-To: <7b23d2d26d717b8e14ba137c94b70943f1ae4b5c.1557769318.git.len.brown@intel.com>

From: Len Brown <len.brown@intel.com>

Syntax update only -- no logical or functional change.

In response to the new multi-die/package changes, update variable names
to use the more generic thermal "zone" terminology, instead of "package",
as the zones can refer to either packages or die.
