dock: introduce .uevent for devices in dock, eg libata
dock's uevent reported itself, not ata. It might be difficult to find an ata device just according to a dock. This patch introduces docking ops for each device in a dock. when docking, dock driver can send device specific uevent. This should help dock station too (not just bay) Signed-off-by: Shaohua Li <shaohua.li@intel.com> Acked-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Len Brown <len.brown@intel.com>
