From: Bartlomiej Zolnierkiewicz Date: Fri, 1 Feb 2008 22:09:22 +0000 (+0100) Subject: ide-cd: re-organize handling of quirky devices X-Git-Tag: v2.6.25-rc1~1078^2~70 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e59724c7db9afd14827f1b737605f54d47f2d226;p=linux-2.6 ide-cd: re-organize handling of quirky devices Re-organize handling of quirky devices: * Add struct cd_list_entry, ide_cd_quirks_list[] and ide_cd_flags() helper. * Set flags returned by ide_cd_flags() in ide_cdrom_setup(). * Add IDE_CD_FLAG_VERTOS_{300_SDD,600_ESD} and IDE_CD_FLAG_SANYO_3CD flags. * Move device quirks from ide_cdrom_setup() to ide_cd_quirks_list[]. * Rename IDE_CD_FLAG_NEC260 to IDE_CD_FLAG_PRE_ATAPI12 and handle quirky Stingray 8X CD-ROM using ide_cd_quirks_list[]. * Add IDE_CD_FLAG_FULL_CAPS_PAGE flag and handle quirky ACER 50X CD-ROM / WPI 32X CD-ROM using ide_cd_quirk_list[]. * Add IDE_CD_FLAG_PLAY_AUDIO_OK flag and handle quirky MATSHITA DVD-ROMs using ide_cd_quirks_list[]. * Add IDE_CD_FLAG_LE_SPEED_FIELDS flag and handle quirky ACER/AOpen 24X CD-ROM using ide_cd_quirk_list[]. * Fix some comments about quirky devices while at it. There should be no functionality changes caused by this patch.
