[PATCH] spi: set kset of master class dev explicitly

<quote Imre Deak from Thu, 12 Jan 2006 21:18:54 +0200>
  In order for spi_busnum_to_master to work spi master devices must be linked
  into the spi_master_class.subsys.kset list.  At the moment the default
  class_obj_subsys.kset is used and we can't enumerate the master devices.
