ide-cd: move VERBOSE_IDE_CD_ERRORS code to ide-cd_verbose.c
* 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: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
