For IVB and older on the CPU side we can only have eDP on port A, DP ports can only be on the PCH side. On VLV we have only CPU side eDP/DP ports, no PCH. So the condition for the disabling sequence we need for CPU ports is port == A || IS_VLV. This allows us to remove is_cpu_edp() completely in a later patch. v2: - simplify (and fix) the condition for CPU side ports and adjust the commit message accordingly (Daniel) Signed-off-by: Imre Deak --- drivers/gpu/drm/i915/intel_dp.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index c21fa4f..bd17887 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -1372,6 +1372,8 @@ static void intel_dp_get_config(struct intel_encoder *encoder, static void intel_disable_dp(struct intel_encoder *encoder) { struct intel_dp *intel_dp = enc_to_intel_dp(&encoder->base); + enum port port = dp_to_dig_port(intel_dp)->port; + struct drm_device *dev = encoder->base.dev; /* Make sure the panel is off before trying to change the mode.
