From 46d0e9e091ba5dd29cac7543e97084540da9c4b7 Mon Sep 17 00:00:00 2001 From: "Lee, Chun-Yi" Date: Sat, 9 Jan 2010 21:16:52 +0800 Subject: [PATCH] msi-laptop: Support standard ec 66/62 command on MSI notebook and nebook Suppport standard ec 66/62 command on MSI notebook and nebook. MSI netbook and notebook already support 66/62 command, so, add new get_state function, and put the old model to non-standard model, but driver still support those old model.
