Because the function didn't produce the desired result without it, ahem.
What I have in the back of my mind is that some boards have more than one I2C
controller chip.   Some will have one controller chip on SOC and one on the
motherboard.   How must  the function be implemented to support that case?
Unfortunately, I have only targets with one I2C controller on-SOC with which
to perform tests.

/sys/bus/i2c/drivers contains the following directories:

dummy      egalax_ts  ov5642     sgtl5000

A simple recursive_action without explicitly opening these directories
produces no results.    Probably there is a way to invoke it so that the
readdir isn't needed, but I didn't discover it.    Assuming that there is
such such a way, I wonder if it would cover the multi-controller case?   I
need to study the I2C driver to learn how sysfs is laid out in that situation.

Thanks, Souf: my toolchain produced a much more obscure error message whose
meaning I could not discern.

Best wishes,
Alison
