From 9814f6b34be5179849c0872e81eb99286ef4b051 Mon Sep 17 00:00:00 2001 From: Steve Brown Date: Mon, 7 Feb 2011 17:10:39 -0700 Subject: [PATCH] ath9k: Remove redundant beacon_interval The variable appears in both ath_softc and ath_beacon_config. The struct ath_beacon_config is embedded in ath_softc. The redundant variable was added by commit id 57c4d7b4c4986037be51476b8e3025d5ba18d8b8.
