drm/radeon: silence GCC warning on 32 bit
Building radeon_ttm.o on 32 bit x86 triggers a warning:
In file included from include/asm-generic/bug.h:13:0,
drivers/gpu/drm/radeon/radeon_ttm.c: In function 'radeon_ttm_gtt_read':
include/linux/kernel.h:712:17: warning: comparison of distinct pointer types lacks a cast [enabled by default]
(void) (&_min1 == &_min2); \
drivers/gpu/drm/radeon/radeon_ttm.c:938:22: note: in expansion of macro 'min'
ssize_t cur_size = min(size, PAGE_SIZE - off);
Silence this warning by using min_t(). Since cur_size will never be
negative and its upper bound is PAGE_SIZE, we can change its type to
size_t and use min_t(size_t, [...]) here.
