From 64ba9a54c60990416c4098c63792c37d8fccb9e1 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 30 Apr 2010 11:30:44 -0700 Subject: [PATCH] iwlwifi: add iwl_sta_id() In places where the station struct is guaranteed to exist (presumably), use this helper to get the station ID out of it (and warn if there's no station struct after all).
