[PATCH 3.16 213/294] iio: adc: fix building on 64-bit

[Ben Hutchings]

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@xxxxxxxx>

On the 3.16 kernel, we get a harmless warning:

drivers/iio/adc/exynos_adc.c: In function 'exynos_adc_get_version':
drivers/iio/adc/exynos_adc.c:112:9: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

Upstream commit e49d99e0ecc8 ("iio: adc: exynos_adc: Add exynos_adc_data
structure to improve readability") in 3.17 removed the function, so
we can't backport a fix from upstream, but changing the cast to
use uintptr_t is the obvious fix.
