Subject: [PATCH 1/5] rt2x00: Minor optimizazion in txdone path
Date: Wed, 7 Sep 2011 20:10:02 +0200 [thread overview]
Message-ID: <201109072010.04023.IvDoorn@gmail.com> (raw)
From: Helmut Schaa <helmut.schaa@googlemail.com>
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.
