    When attempting to setup up a gpio hog, device probing would repeatedly
    fail with -EPROBE_DEFERED errors. It was caused by a circular dependency
    between the gpio and pinctrl frameworks. If the gpio-ranges property is
    present in device tree, then the gpio framework will handle the gpio pin
    registration and eliminate the circular dependency.
    
    See Christian Lamparter's commit a86caa9b ("pinctrl: msm: fix
    gpio-hog related boot issues") for a detailed commit message that
    explains the issue in much more detail. The code comment in this commit
    came from Christian's commit.
