This sounds like a band-aid. Isn't the gpio driver going to keep probing
all the pins that are not supposed to be accessed due to security
constraints? What exactly is failing in the gpio case?

Also, I thought we were getting rid of the ownership checks? Or at
least, putting them behind some debug kernel feature check or something?
