Subject: ide-floppy: ->{srfp,wp} -> IDE_AFLAG_{SRFP,WP}
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=49cac39e71bd6bbcf934c6ba837e21503902c088;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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.
