    ide: Convert to bdops->check_events() · 5b03a1b1
    Tejun Heo authored
    Convert ->media_changed() to the new ->check_events() method.  The
    conversion is mostly mechanical.  The only notable change is that
    cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT.
    It used to return -EINVAL which would be treated as media changed.  As
    media changer isn't supported anyway, this doesn't make any
    difference.
    
    This makes ide emit the standard disk events and allows kernel event
    polling.  Currently, only MEDIA_CHANGE event is implemented.  Adding
    support for EJECT_REQUEST shouldn't be difficult; however, given that
    ide driver is already deprecated, it probably is best to leave it
    alone.
