Got it! Like the following patch? Thank's Joey Lee >From c9308632bd0b17005d3f6cd2eaf27e1d053f40fb Mon Sep 17 00:00:00 2001 From: Lee, Chun-Yi <[email protected]> Date: Sat, 28 May 2011 09:02:41 +0800 Subject: [PATCH] acer-wmi: schedule threeg and interface sysfs for feature removal we can now autodetect internal 3G device and already have the threeg rfkill device. So, we plan to remove threeg sysfs support for it's no longer necessary. We also plan to remove interface sysfs file that exposed which ACPI-WMI interface that was used by acer-wmi driver. It will replaced by information log when acer-wmi initial. We keep it around for userspace compatibility reasons, schedule removal in 2012.
