Title
drm/rockchip: vop: fix possible null-ptr-deref in vop_bind()
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: vop: fix possible null-ptr-deref in vop_bind() It will cause null-ptr-deref in resource_size(), if platform_get_resource() returns NULL, move calling resource_size() after devm_ioremap_resource() that will check 'res' to avoid null-ptr-deref.
