From 943547abdfe9b4e27e36a25987909619908dffbf Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sun, 2 Dec 2007 03:47:01 +0100 Subject: [PATCH] pata_amd/pata_via: de-couple programming of PIO/MWDMA and UDMA timings * Don't program UDMA timings when programming PIO or MWDMA modes. This has also a nice side-effect of fixing regression added by commit 681c80b5d96076f447e8101ac4325c82d8dce508 ("libata: correct handling of SRST reset sequences") (->set_piomode method for PIO0 is called before ->cable_detect method which checks UDMA timings to get the cable type). * Bump driver version.
