CVE-2023-54047

Description

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

drm/rockchip: dw_hdmi: cleanup drm encoder during unbind

This fixes a use-after-free crash during rmmod.

The DRM encoder is embedded inside the larger rockchip_hdmi, which is allocated with the component. The component memory gets freed before the main drm device is destroyed. Fix it by running encoder cleanup before tearing down its container.

[moved encoder cleanup above clk_disable, similar to bind-error-path]
