From c8381fdcab98b74f670d879097bab35d97d88400 Mon Sep 17 00:00:00 2001 From: Mohamed Abbas Date: Fri, 28 Mar 2008 16:21:05 -0700 Subject: [PATCH] iwlwifi: add notification infrastructure to iwlcore This patch add notification function to be called by low level iwl driver to notify iwlcore with current state. This function will call iwlcore subsystem with the new state. This will help make the code more consistent and easy to extend. For example the rf-kill need to know when the driver in init, start, stop or remove state. Instead doing the same call in 3945 and 4965, we just do it from this function.
