From 49cac39e71bd6bbcf934c6ba837e21503902c088 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 10 Oct 2008 22:39:38 +0200 Subject: ide-floppy: ->{srfp,wp} -> IDE_AFLAG_{SRFP,WP} Add IDE_AFLAG_{SRFP,WP} drive->atapi_flags and use them instead of ->{srfp,wp} struct ide_floppy_obj fields. There should be no functional changes caused by this patch.
