Applied this on my Quartz64 Model A (RK3566) where I currently am
having a play with some SPI devices. Now gpioinfo correctly shows
the interrupt pin as being in use.

Before:
         line   3:      unnamed       unused   input  active-high 

After:
         line   3:      unnamed  "interrupt"   input  active-high [used]
