From acaa0f5f675ccf6b8a3a11a933419068b1ea1f46 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 10 Oct 2008 22:39:36 +0200 Subject: ide: add ide_io_buffers() helper * Make ->io_buffers method return number of bytes transferred. * Use ide_end_request() instead of idefloppy_end_request() in ide_floppy_io_buffers() and then move the call out to ide_pc_intr(). * Add ide_io_buffers() helper and convert ide-{floppy,scsi}.c to use it instead of ide*_io_buffers(). There should be no functional changes caused by this patch.
