There are two bugs in driver/spi/spic.
(1) when spi master is deconstructed, it's parent device node's reference count
is not decreased. It exists from kernel 2.6.28 to 3.0. It sometimes results in
memory leak. Example, its's parent device node will be always reference by
others and never be released.
(2) when spi device is created, its parent device node should be spi master. It
should be keep consistent with function spi_unregister_master. it exists in
2.6.39 and 3.0
