    Subject[PATCH 36/63] ide-cd: move VERBOSE_IDE_CD_ERRORS code to ide-cd_verbose.c
    Date

    * 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:
