Developer boards often play by different rules than product boards, and one
example is the potential need to hotplug SPI devices and/or controllers.

up the spi bus master, and will likely need spi_new_device() to provide the
board info based on the board that was hotplugged. Of course, you'd later
call at least spi_unregister_device() when that board is removed.

the driver guarantees that it won't submit any more such messages.
