From baaffe67b5b33e4215409669226ef623cb65e15c Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Thu, 3 Jun 2010 10:51:43 +0200 Subject: [PATCH] rt2x00: Reverse calling order of bus write_tx_desc and driver write_tx_desc. For rt2800 reverse the calling order of rt2x00pci_write_data and rt2800pci_write_data. Currently rt2800pci_write_data calls rt2x00pci_write_data as there can be only 1 driver callback function specified by the driver. Reverse this calling order by introducing a new driver callback function, called write_tx_datadesc, which is called from the bus-specific write_tx_data functions. Preparation for futher cleanups in the skb data handling of rt2x00.
