From 342cdb6d4739cee430efc3eafcacd1605db66036 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 20 Jul 2007 01:11:55 +0200 Subject: [PATCH] ide: make ide_get_best_pio_mode() print info if overriding PIO mode * Print info about overriding PIO mode in ide_get_best_pio_mode(). * Remove info about overriding PIO mode from cmd64{0,x} host drivers. * Remove no longer needed ide_pio_data_t.overridden field.
