In the Linux kernel, the following vulnerability has been resolved:
drm/msm/disp/dpu1: avoid clearing hw interrupts if hw_intr is null during drm uninit
If edp modeset init is failed due to panel being not ready and
probe defers during drm bind, avoid clearing irqs and dereference
hw_intr when hw_intr is null.
BUG: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
