From 278fc73c0c6014bc2f55bce898bdeaa322bf4aba Mon Sep 17 00:00:00 2001 From: Wey-Yi Guy Date: Mon, 14 Jun 2010 17:09:53 -0700 Subject: [PATCH] iwlwifi: move agn specific rx related code to iwl-agn-rx.c To avoid having unnecessary functions in iwlcore.ko, those that are not shared by agn and 3945, move agn specific rx related code to iwl-agn-rx.c.
