From a986c75a7df027d2c649a8f087be9417372cbfb3 Mon Sep 17 00:00:00 2001 From: Alexander Kappner Date: Mon, 2 Apr 2018 11:27:01 -0700 Subject: [PATCH] platform/x86: thinkpad_acpi: Add 2nd Fan Support for Thinkpad P50 The Thinkpad P50 has 2 fans. Add the 2FAN quirk so the tpacpi driver properly reports both fan speeds. Because the P50 doesn't report the version of its EC controller, we need to identify it by BIOS version (N1).
