The purpose of commit 1e8a52e1
"spi: By default setup spi_masters with 1 chipselect and dynamics bus number"
is to avoid setting default value for bus_num and num_chipselect in spi master
drivers. So let's remove the duplicate code.

Use devm_spi_register_master() to make cleanup paths simpler,

Due to hardware limitations of the spi/flash frontend of the EBU we need to set
the SPI_MASTER_HALF_DUPLEX flag.

Rather than calling m->complete() directly we choose the sane way and call
spi_finalize_current_message instead.

CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Bill Pemberton has done most of the legwork on this series. I've used
his script to purge the attributes from the drivers/gpio tree.

The external bus unit (EBU) found on the FALCON SoC has spi emulation that is
designed for serial flash access. This driver has only been tested with m25p80
type chips. The hardware has no support for other types of spi peripherals.
