CVE-2026-80658

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

drm/rockchip: dw_dp: Fix null-ptr-deref in dw_dp_remove()

Attempting to access driver data in the platform driver ->remove()

callback may lead to a null pointer dereference since there is no

guaranty that the component ->bind() callback invoking

platform_set_drvdata() was executed.

A common scenario is when Rockchip DRM driver didn't manage to run

component_bind_all() because of an (unrelated) error causing early

return from rockchip_drm_bind().

Drop the unnecessary call to platform_get_drvdata() and, instead,

reference the target device structure via platform_device.
