Message-ID: <20061201215318.GC3370@tuxdriver.com>
Date: Fri, 1 Dec 2006 16:53:26 -0500
From: "John W. Linville" <linville@...driver.com>
To: netdev@...r.kernel.org
Cc: ivdoorn@...il.com, johannes@...solutions.net
Subject: [RFC] rt2400: fix breakage from API changes
Here's my whack at fixing-up the rt2400pci driver to compile, since
the recent API changes broke it. This only covers that one driver,
so lots more (albeit similar) work needs to be done to cover the
other rt2x00 family drivers.
Ivo and Johannes, please take a quick look to see if I'm obviously
missing something or handling something incorrectly. I don't have
the hardware in questions, so this is completely untested. :-)
