[PATCH 1/3] staging:iio:magnetometer:ak8975 Don't use irq_to_gpio()

[Stephen Warren <swarren@nvidia.com>]

Tegra doesn't have irq_to_gpio() any more, and ak8975 is included in
tegra_defconfig. This causes a build failure. Solve this with a heavy-handed
method for now.

I suspect the long-term solution is to pass both the IRQ and GPIO IDs
to the driver; the GPIO ID coming from either platform data, or perhaps
enhancing struct i2c_client to add a gpio field alongside irq.

Russell, now that irq_to_gpio() is going away, can you comment on how
you'd like to fix drivers that do this kind of thing? Thanks.
