drivers/gpu/drm/vmwgfx/vmwgfx_resource.c: alloc with no test

[Fengguang Wu <fengguang.wu@xxxxxxxxx>]

Hi Thomas,

FYI, coccinelle warns about

drivers/gpu/drm/vmwgfx/vmwgfx_resource.c:1355:1-13: alloc with no test, possible model on line 1402

vim +1355 drivers/gpu/drm/vmwgfx/vmwgfx_resource.c
  1345	
  1346		memcpy(srf->mip_levels, req->mip_levels, sizeof(srf->mip_levels));
  1347		srf->num_sizes = num_sizes;
  1348		user_srf->size = size;
  1349	
  1350		srf->sizes = kmalloc(srf->num_sizes * sizeof(*srf->sizes), GFP_KERNEL);
  1351		if (unlikely(srf->sizes == NULL)) {
  1352			ret = -ENOMEM;
  1353			goto out_no_sizes;
  1354		}
> 1355		srf->offsets = kmalloc(srf->num_sizes * sizeof(*srf->offsets),
  1356				       GFP_KERNEL);
  1357		if (unlikely(srf->sizes == NULL)) {
  1358			ret = -ENOMEM;
  1359			goto out_no_offsets;
  1360		}
  1361	
  1362		user_sizes = (struct drm_vmw_size __user *)(unsigned long)
  1363		    req->size_addr;
  1364	
  1365		ret = copy_from_user(srf->sizes, user_sizes,

Which is likely a copy/paste error introduced by commit
