Pass a crtc_state to it and find whether the pipe has an encoder of a given type by looking at the drm_atomic_state the crtc_state points to.
Until recently i9xx_get_refclk() used to be called indirectly from vlv_force_pll_on() with a dummy crtc_state. That dummy crtc state is not converted to be part of a full drm atomic state, so add a WARN in case someone decides to call that again with such a dummy state. v2: Warn if there is no connectors for a given crtc. (Daniel) Replace comment i9xx_get_refclk() with a WARN_ON().
