As reported by Uwe Kleine-K�nig, the interrupt trigger is first configured by DT and then reconfigured to edge. This results in a failure on EPROBE_DEFER, or if the module is unloaded and reloaded.
A second crash happens on module reload due to a missing call to the common IRQ free code when using polled interrupts. With these fixes in place, it becomes possible to load and unload the kernel modules a few times without it crashing.
