From 9eece5d9c6e0316f17091e37ff3ec87331bdedf3 Mon Sep 17 00:00:00 2001 From: Oleksandr Andrushchenko Date: Wed, 23 May 2018 14:36:30 +0300 Subject: [PATCH] drm/xen-front: fix pointer casts Building for a 32-bit target results in warnings from casting between a 32-bit pointer and a 64-bit integer. Fix the warnings by casting those pointers to uintptr_t first.
