X-Git-Tag: MMI-PSA29.97-13-9~20521^2~509 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f2f1794835f1d8900d2b15d114c54e70c849809b;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git staging: iio: ak8975: add platform data. As some of the platform not support irq_to_gpio, we pass gpio port by platform data.
