From 7b8aca65db5dd1aaa6dc1e11f6bfcc0ecd6bc8a4 Mon Sep 17 00:00:00 2001 From: "Lee, Chun-Yi" Date: Tue, 31 May 2011 14:52:22 +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.
