From ea68d270ff55bcdfa5d07697eb68103b5b02c7bb Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Wed, 23 Jul 2008 19:56:01 +0200 Subject: [PATCH] ide-floppy: convert to using the new atapi_flags (take 2) while at it, remove PC_FLAG_ZIP_DRIVE from the packed command flags altogether and query the drive type through drive->atapi_flags. v2: ide-floppy fix. There should be no functionality change resulting from this patch.
