From c8f16138b5099bfd928942c3775aaecfd649e9e5 Mon Sep 17 00:00:00 2001 From: Reinette Chatre Date: Fri, 27 Feb 2009 16:21:22 -0800 Subject: [PATCH] iwlwifi: fix *pci_probe error flow for iwlagn: - Have to free eeprom of version check fails - otherwise we end up with memory leak. - Include removal of workqueue (created in _setup_deferred_work) in error handling. for iwl3945: - Fix a few places to jump to correct error handling. - Reorganize error handling to match with code flow. - Include iwl_free_channel_map as part of error handling. - Include releasing eeprom as part of error handling.
