gpio: gpio driver for max7301 SPI GPIO expander
Maxim's MAX7301 is an SPI GPIO expander with 28 GPIOs. Note: MAX7301's
interrupt feature is not supported yet.
[akpm@linux-foundation.org: coding-style fixes]
[g.liakhovetski@pengutronix.de: Fix inaccuracies in comments, check spi_setup()
return code, mask off high byte in max7301_read()]
