This is "drm/radeon: remove load callback" v2, the only changes
were made are adding "ddev->dev_private = rdev;", right after
the allocation of "struct radeon_device". Patch v2 2-7 mostly
describes simple "rdev->ddev" to "rdev_to_drm(rdev)" to suit
Patch v2 1/7.
Please be aware that these 7 patches depends on each other.
Thank you.
