Since there will be some changes to how iio_priv_to_dev() is implemented,
it could be that the helper becomes a bit slower, as it will be hidden away
in the IIO core.
For this driver, the IIO device can be passed directly as a parameter to
the ping_read() function, thus making it immune to the change of
iio_priv_to_dev().
