From d0a5191dcf5f37cf0942c4b65fa4a2c975631c0b Mon Sep 17 00:00:00 2001 From: Marcin Slusarz Date: Sun, 3 Feb 2013 19:12:49 +0100 Subject: [PATCH] drm/nv40/therm: reset temperature sensor on init MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Current uninitialized sensor detection does not work for me on nv4b and sensor returns crazy values (>190°C). It stabilises later, but it's too late - therm code shutdowns the machine... Let's just reset it on init.
