From 5c29d58f471099401513e2e567f6c28001bb0f13 Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Wed, 18 Jul 2007 23:45:38 -0300 Subject: ACPI: thinkpad-acpi: export EV_SW SW_RADIO events The expected user case for the radio slider switch on a ThinkPad includes interfacing to applications, so that the user gets an offer to find and associate with a wireless network when the switch is changed from disabled to enabled (ThinkVantage suite). Export the information about the switch state, and switch change events as an EV_SW SW_RADIO event over the input layer.
