From 4d7ede7f5ad58c5316335b9018ddef58bd687def Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Wed, 26 May 2010 13:33:31 -0400 Subject: [PATCH] rt2x00: do not shortcut rt2x00lib_config_antenna This function was exiting early if the existing diversity settings were unchanged. Unfortunately, in some cases the antenna configuration is not initialized at all. https://bugzilla.kernel.org/show_bug.cgi?id=14751 Signed-off-by: John W.
