14ac00e033 spi: drop owner assignment from platform_drivers 
A platform_driver does not need to set an owner, it will be populated by the
driver core.

78e39523b8 spi: Remove explictly set bus_num and num_chipselect to default setting 
The purpose of commit 1e8a52e18c
"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.

354312f16e spi: Remove duplicate code to check chip_select 
In spi_add_device(), we have the code to validate spi->chip_select.
So remove the duplicate code in various drivers.

737a7c4380 spi/mips-lantiq: make use of spi_finalize_current_message

spi_finalize_current_message instead.

fd4a319bc9 spi: Remove HOTPLUG section attributes 
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.

6cd3c7e2b1 SPI: MIPS: lantiq: add FALCON spi driver 
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.
