CVE-2026-80658

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

drm/rockchip: dwdp: Fix null-ptr-deref in dwdp_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 platformsetdrvdata() was executed.

A common scenario is when Rockchip DRM driver didn't manage to run componentbindall() because of an (unrelated) error causing early return from rockchipdrmbind().

Drop the unnecessary call to platformgetdrvdata() and, instead, reference the target device structure via platform_device.
