From e0ee792b75a5cf1b23acfeae7ce3c386f805b20b Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 3 Dec 2009 20:32:10 +0100 Subject: [PATCH] pata_it8213: fix UDMA handling Driver should program the cycle timing not the mode number (doing the latter results in wrong timings being used). There shouldn't be any problems with it as IDE it8213 host driver has been doing it this way for years.
