Hi all,

After merging the drm tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

In file included from include/linux/list.h:9:0,
from include/linux/wait.h:7,
from include/linux/wait_bit.h:8,
from include/linux/fs.h:6,
from include/linux/highmem.h:5,
from drivers/gpu/drm/drm_memory.c:36:
drivers/gpu/drm/drm_memory.c: In function 'drm_get_max_iomem':
include/linux/kernel.h:808:16: warning: comparison of distinct pointer types lacks a cast
(void) (&max1 == &max2); \

^~~~~
drivers/gpu/drm/drm_memory.c:159:15: note: in expansion of macro 'max'
max_iomem = max(max_iomem, tmp->end);

Introduced by commit

82626363a217 ("drm: add func to get max iomem address v2")

tmp->end is a resource_size_t ...
