Downgrade this to a debug printk so that we're quiet here. This allows multiple drivers to request a CPU's regulator so that CPUfreq and AVSish drivers can coexist. The downside of this approach is that whoever gets to debugfs first the others who come later to not have any debugfs attributes associated with them.
