The subsystem calls the driver to transfer a single transfer while
|

queuing transfers that arrive in the meantime. When the driver is
|

finished with this transfer, it must call
|

spi_finalize_current_transfer() so the subsystem can issue the next

transfer. This may sleep. Note: transfer_one and transfer_one_message
|

are mutually exclusive; when both are set, the generic subsystem does

not call your transfer_one callback.

Return values:

negative errno: error

0: transfer is finished
