From e6148917db2c223fa7edd3dfb64d99756a86b452 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Fri, 23 Jan 2009 13:45:15 -0800 Subject: iwl3945: Use iwl-eeprom.c routines By adding the eeprom ops to the 3945 code, we can now use the iwlcore eeprom routines (defined in iwl-eeprom.c). We also removed the heavy eeprom39 reference from iwl_priv and use the eeprom pointer instead. Signed-off-by: Samuel Ortiz Signed-off-by: Reinette Chatre Signed-off-by: John W.
