From 990aa6d7b28d26bf22171410b49f191e8e9b09fc Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Wed, 14 Nov 2012 12:39:52 +0200 Subject: iwlwifi: rename functions in transport layer 1) s/tx_queue/txq for the sake of consistency. 2) s/rx_queue/rxq for the sake of consistency. 3) Make all functions begin with iwl_pcie_ iwl_queue_init and iwl_queue_space are an exception since they are not PCIE specific although they are in pcie subdir. 4) s/trans_pcie_get_cmd_string/get_cmd_string it is much shorter and used in debug prints which are long lines. 5) s/iwl_bg_rx_replenish/iwl_pcie_rx_replenish_work this better emphasizes that it is a work 6) remove invalid kernelDOC markers pcie/tx.c and pcie/trans.c still needs to be cleaned up.
