From 5562092131bc2f055048df7fe3a536592fa6f04d Mon Sep 17 00:00:00 2001 From: Meenakshi Venkataraman Date: Thu, 15 Mar 2012 13:27:02 -0700 Subject: iwlwifi: move iwl_full_rxon_required and mark it static iwl_full_rxon_required is used only in iwl-agn-rxon.c. Move it there and mark it static. Signed-off-by: Meenakshi Venkataraman Signed-off-by: Wey-Yi Guy Signed-off-by: John W.
