    "title": "pinctrl: equilibrium: fix warning trace on load",
    "summary": "In the Linux kernel, the following vulnerability has been resolved: pinctrl: equilibrium: fix warning trace on load The callback functions 'eqbr_irq_mask()' and 'eqbr_irq_ack()' are also called in the callback function 'eqbr_irq_mask_ack()'. This is done to avoid source code duplication. The problem, is that in the function 'eqbr_irq_mask()' also calles the gpiolib function 'gpiochip_disable_irq()' This generates the following warning trace in the log for every gpio on load.
