From 14ffc8e43369a30ef59dca9d7f0e7f59776ca368 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 5 May 2017 21:46:30 +0200 Subject: [PATCH] iio: adc: fix building on 64-bit 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.
