    drm/i915: fix GMCH power reporting · d270ae34
    Jesse Barnes authored
    The IPS driver needs to know the current power consumption of the GMCH
    in order to make decisions about when to increase or decrease the CPU
    and/or GPU power envelope.  So fix up the divisions to save the results
    so the numbers are actually correct (contrary to some earlier comments
    and code, these functions do not modify the first argument and use it
    for the result).
