[PATCH] drm/stm: check pitch and size calculations even if !CONFIG_MMU

From: Benjamin Gaignard
Date: Tue Jan 30 2018 - 10:24:12 EST


In all cases we have to check pitch and size calculations.
Rely on drm_gem_cma_dumb_create for no MMU cases.

Fixes: 21f815bf773c ("drm/stm: drv: Improve data transfers")
