"""Update the ``rpi.geq`` section of a camera tuning dict.
``tuning`` will be updated in-place to set the geq offest to the given value.
The default 65535 is the maximum allowed value. This means
the brightness will always be below the threshold where averaging is used.
:param tuning: the raspberry pi tuning file. This will be updated in-place to
set the geq offest to the given value.
:param offset: The desired green equalisation offset. Default 65535. The default is
the maximum allowed value. This means the brightness will always be below the
threshold where averaging is used. This is default as we always need the green
equalisation to averages the green pixels in the red and blue rows due to the
chief ray angle compensation issue when the the stock lens is replaced by an
objective.
