Hartley pointed out that the patch I posted to remove the irq internals
fiddling from ep93xx_gpio_dbg_show does not function as expected. It
will print [interrupt] beside all pins which are capable of being
interrupts, not just those which are currently configured as interrupts.
The best solution is just to remove the custom ep93xx gpio debugfs
function all together. The generic gpiolib one is good enough.

This is presently sitting in rmk's patch tracking system. I take it I
should drop it from there?

Actually, no. I missed it was under arch/arm instead of drivers/gpio.
I'll drop it from my tree.
