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

    Input: mtk-pmic-keys – fix possible null pointer dereference

    In mtk_pmic_keys_probe, the regs parameter is only set if the button is
    parsed in the device tree. However, on hardware where the button is left
    floating, that node will most likely be removed not to enable that
    input. In that case the code will try to dereference a null pointer.

    Let’s use the regs struct instead as it is defined for all supported
    platforms. Note that it is ok setting the key reg even if that latter is
    disabled as the interrupt won’t be enabled anyway.
