Description SMASH SMASH 2024-07-17 13:24:07 UTC

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

drm/vc4: hdmi: Unregister codec device on unbind

On bind we will register the HDMI codec device but we don't unregister
it on unbind, leading to a device leakage. Unregister our device at
unbind.
