Add REQ_TYPE_{SENSE,ATA_PC} requests handling to cdrom_do_block_pc() and remove cdrom_do_packet_command(). There should be no functionality changes caused by this patch. Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

cdrom_do_pc_continuation() is now identical to cdrom_do_newpc_cont() so just always use the latter function. Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Add handling of REQ_TYPE_{SENSE,ATA_PC} requests to cdrom_newpc_intr() (please note that these requests never have 'bio' attached to them and they never use DMA), then remove no longer needed cdrom_pc_intr(). There should be no functionality changes caused by this patch. Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Move lba_to_msf() and msf_to_lba() to <linux/cdrom.h> (use 'u8' type instead of 'byte' while at it). * Remove msf_to_lba() copy from drivers/cdrom/cdrom.c. Acked-by: NJens Axboe <jens.axboe@oracle.com> Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Rename ide-cd kernel module to ide-cd_mod in preparation to moving code out from ide-cd.[c,h]. Add MODULE_ALIAS("ide-cd") to preserve compatibility. * Move VERBOSE_IDE_CD_ERRORS code from ide-cd.[c,h] to ide-cd_verbose.c. ide-cd_verbose.c is IDE subsystem independent and may be easily converted into generic library usable by other drivers (i.e. libata) if needed. * Add CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS config option to drivers/ide/Kconfig replacing VERBOSE_IDE_CD_ERRORS define. Make this config option enabled by default and visible only if CONFIG_EMBEDDED is defined. before the patch: text data bss dec hex filename 22841 360 1056 24257 5ec1 drivers/ide/ide-cd.o after the patch w/ CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS=y: text data bss dec hex filename 22857 360 1056 24273 5ed1 drivers/ide/ide-cd_mod.o after the patch w/ CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS=n: text data bss dec hex filename 15091 360 1056 16507 407b drivers/ide/ide-cd_mod.o Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

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.

ide_cd_probe() zeroes 'info' prior to calling ide_cdrom_setup() so there is no need to explicitly zero 'info' fields in the latter function. Ditto for fields of CDROM_STATE_FLAGS(), CDROM_CONFIG_FLAGS() and 'cdi' (all are embedded in 'info').
