In the Linux kernel, the following vulnerability has been resolved:drm/i915/bios: Tolerate devdata==NULL in intel_bios_encoder_supports_dp_dual_mode()If we have no VBT, or the VBT didn t declare the encoderin question, we won t have the devdata for the encoder.Instead of oopsing just bail early.We won t be able to tell whether the port is DP++ or not,but so be it.(cherry picked from commit 26410896206342c8a80d2b027923e9ee7d33b733)
