From 4c93067ea9e5eca9d975bec74dae641228ac1bbe Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 15 Jul 2008 21:22:02 +0200 Subject: ide-floppy: add more debugging to idefloppy_pc_intr() Add more debugging to idefloppy_pc_intr() to match ide-tape's idetape_pc_intr(). While at it: * Correct the first debug message. * Log device name with "DMA finished" message. This is a preparation for adding generic ide_pc_intr() helper.
