Description

In the Linux kernel, the following vulnerability has been resolved:

drm/radeon: Do not kfree() devres managed rdev

Since the allocation of the drivers main structure was changed to devm_drm_dev_alloc() rdev is managed by devres and we shouldn't be calling kfree() on it.

This fixes things exploding if the driver probe fails and devres cleans up the rdev after we already free'd it.

(cherry picked from commit 16c0681617b8a045773d4d87b6140002fa75b03b)
