From 8e714a074bc4da070807d019d4287dcd32af55f5 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 19 Jan 2010 01:47:29 -0800 Subject: [PATCH] ide-timings: use ->pio_mode value to determine fastest PIO speed Use the current PIO mode value instead of the physical maximum one to determine the fastest allowed PIO for shared PIO/DMA timings. Affected host drivers: amd74xx and via82cxxx. [ Update comment to match -DaveM ] Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: David S.
