        src/sys/dev/usb: ugen.c
 
 Log Message:
 Putting a device into the unconfigured state by an ioctl seems legitimate,
 so check for a non-NULL configuration descriptor before dereferencing.
 Should fix a crash reported by Nicolas Joly per PR kern/41048.
 (It still doesn't look good that the ioctl which unconfigures the device
 returns EIO -- either it is legitimate or it isn't -- but since this
 is a pullup candidate I don't dare to change user visible behaviour.)
