        src/sys/dev/usb: uhidev.c uhidev.h
 
 Log Message:
 Fix a dereference if a softc pointer which can legally be zero, leading
 to a crash reported by Christoph Egger in a followup to PR kern/38528.
 For consistency, keep track of the device_t pointer to child devices
 rather than the softc. We really shouldn't mess with child's softc data.
