It pushes the BKL down into the i2c driver. The intention is to remove
the big kernel lock ioctl method from the file_operations structure so
that we can work on getting rid of the big kernel lock for good. It's one
of a series of patches that give me an x86-32 tree with no ->ioctl method
at all.

Similar activity is going on for the other calls made under the BKL the
goal being to push it down into drivers and then eliminate it.
