From 31937c423ed3a13613b3aa7459e7405dd428f2d8 Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Wed, 7 Sep 2011 20:10:02 +0200 Subject: rt2x00: Minor optimizazion in txdone path We can save an indirect function call + some instructions for fetching the actual function pointer by passing the driver specific txwi pointer directly from rt2800pci/rt2800usb to rt2800lib instead of using the rt2800_drv_get_txwi callback.
