Subject: [PATCH V2 2/4] staging:iio:magnetometer:ak8975 Don't use irq_to_gpio()

Tegra doesn't have irq_to_gpio() any more, and ak8975 is included in
tegra_defconfig. This causes a build failure.

Instead, obtain the GPIO ID corresponding to the chip's IRQ from the new
i2c_client field irq_gpio.

Signed-off-by: Stephen Warren <swarren@...dia.com>

v2: Obtain eoc_gpio from i2c_client, instead of hard-coding it as an
invalid value.
