From 7bdea96a1bbae75e7922584e3ae37fb9ad6cb79a Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Sun, 4 Aug 2013 14:22:00 +0530 Subject: [PATCH] ath9k: Remove "shared_chain_lnadiv" This variable is redundant since we can use common->bt_ant_diversity to determine if diversity has to be enabled/disabled.
