CVE-2023-54047

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/rockchip: dw_hdmi: cleanup drm encoder during unbind<br /> <br /> This fixes a use-after-free crash during rmmod.<br /> <br /> The DRM encoder is embedded inside the larger rockchip_hdmi,<br /> which is allocated with the component. The component memory<br /> gets freed before the main drm device is destroyed. Fix it<br /> by running encoder cleanup before tearing down its container.<br /> <br /> [moved encoder cleanup above clk_disable, similar to bind-error-path]
