You may look into this patch: e34ff011c70e5f4ef219141711142d5111ae6ebb
for the spi-bcm2835 driver, which did the conversion to the new transfer_one
interface (and framework based GPIO chipselects).
For most parts all you have to do is take the contents of the loop over all the
spi_transfers inside your master->transfer_one_message method and create a new
method with it and assign it to master->transfer_one.
