Subject: [PATCH] drm/cma: Fix 64-bit size_t build warnings

From: Magnus Damm <damm+renesas@...nsource.se>

Fix warnings related to size_t when building for 64-bit architectures:

drivers/gpu/drm/drm_gem_cma_helper.c: In function ‘drm_gem_cma_create’:
drivers/gpu/drm/drm_gem_cma_helper.c:114:4: warning: format ‘%d’ expects argument of type ‘int’, but argument 3 has type ‘size_t’ [-Wformat=]
    size);
    ^
drivers/gpu/drm/drm_gem_cma_helper.c: In function ‘drm_gem_cma_describe’:
drivers/gpu/drm/drm_gem_cma_helper.c:393:4: warning: format ‘%d’ expects argument of type ‘int’, but argument 8 has type ‘size_t’ [-Wformat=]
    off, &cma_obj->paddr, cma_obj->vaddr, obj->size);
