The DPLL multipiler is set up in intel_display.c:i9xx_update_pll() called from i9xx_crtc_mode_set(). There the DPLL multiplier is adjusted so that the SDVO gets a sufficient bus clock. When cloning a CRTC between an SDVO driven encoder and the standard DAC the DAC setup code reseted the multiplier value to 1 thus undoing the correct setup. There is no need to touch the multiplier in the DAC setup code: the correct value (i.e. 1 in case no SDVO encoder is used) is set by i9xx_update_pll() already. A comment at the code suggested that this code is a left over from the days when there was no setup for clone modes.
