Dan Carpenter 40a8d7e492 drm/rockchip: Fix type promotion bug in rockchip_gem_iommu_map() 
[ Upstream commit 6471da5ee3 ]

The "ret" variable is declared as ssize_t and it can hold negative error
codes but the "rk_obj->base.size" variable is type size_t.  This means
that when we compare them, they are both type promoted to size_t and the
negative error code becomes a high unsigned value and is treated as
success.  Add a cast to fix this.
