Looking at irq_set_lockdep_class update patch, what appears to be a simple fix is to simply remove the last parameter from irq_set_lockdep_class call in pinctrl-at91-pio4.c, but I am not even sure if the fix remains legitimate in this case (ie if the corresponding lockdep splat reappears), and I do not have access to corresponding hardware before the deadline, so if that's not already the plan, I suggest to drop this from 4.14 branch.
