From 8b6b33be3280fd776335079124ecd176e6a40797 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Wed, 1 Aug 2007 23:46:46 +0200 Subject: [PATCH] jmicron: PIO fixes * Set transfer mode on the device in jmicron_tuneproc(), also add pio == 255 == "auto-tune" handling. * Use jmicron_tuneproc() in jmicron_config_drive_for_dma(). * Remove no longer needed config_jmicron_chipset_for_pio().
