a3dc3c9eb0 MISC: convert drivers/misc/* to use module_spi_driver()
This patch converts the drivers in drivers/misc/* to use the
module_spi_driver() macro which makes the code smaller and a bit
simpler.

7f3379de9c misc: ad525x_dpot: Add support for SPI module device table matching
Passing device name via platform data, is a leftover from times where
SPI module device table matching was not existent.

* Add id_table and remove old mechanism.
(To my knowledge no intree boards affected)
* Miscellaneous other cleanup.

1f9fa5216e drivers/misc/ad525x_dpot.c: fix typo in spi write16 and write24 transfer counts
This is a bug fix.  Some SPI connected devices using 16/24 bit accesses,
previously failed, now work.

This typo slipped in after testing, during some restructuring.

6c536e4ce8 ad525x_dpot: add support for SPI parts
Split the bus logic out into separate files so that we can handle I2C and
SPI busses independently.  The new SPI bus logic brings in support for a
lot more parts:

	AD5160, AD5161, AD5162, AD5165, AD5200, AD5201, AD5203,
	AD5204, AD5206, AD5207, AD5231, AD5232, AD5233, AD5235,
	AD5260, AD5262, AD5263, AD5290, AD5291, AD5292, AD5293,
	AD7376, AD8400, AD8402, AD8403, ADN2850
