This is wrong as this does not pass anything as input. The function is
called from get_device_system_crosststamp() and the data is passed back
via the system_counterval pointer. It also lacks context.

. Something like this:

   "The core code provides a mechanism to convert the ART base clock to
    the corresponding TSC value without requiring an architecture
    specific function.

    All what is required is to store the ART clocksoure ID and the
    cycles value in the provided system_counterval structure.

    Replace the direct conversion via convert_art_to_tsc() by filling in
    the required data.

    No functional change intended."

Hmm?

Thanks,
