This also gets rid of a call to intel_dsi_pipe_to_port() which we want to remove eventually. v2: add braces to fix else logic (Shobhit) Signed-off-by: Jani Nikula Reviewed-By: Shobhit Kumar Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/intel_dsi.c b/drivers/gpu/drm/i915/intel_dsi.c index 4bb9886fa2cf..dac41046a0cc 100644 --- a/drivers/gpu/drm/i915/intel_dsi.c +++ b/drivers/gpu/drm/i915/intel_dsi.c @@ -197,15 +197,15 @@ static void intel_dsi_enable(struct intel_encoder *encoder) { struct drm_device *dev = encoder->base.dev; struct drm_i915_private *dev_priv = dev->dev_private; - struct intel_crtc *intel_crtc = to_intel_crtc(encoder->base.crtc); struct intel_dsi *intel_dsi = enc_to_intel_dsi(&encoder->base); - enum port port = intel_dsi_pipe_to_port(intel_crtc->pipe); + enum port port; DRM_DEBUG_KMS("\n"); - if (is_cmd_mode(intel_dsi)) - I915_WRITE(MIPI_MAX_RETURN_PKT_SIZE(port), 8 * 4); - else { + if (is_cmd_mode(intel_dsi)) { + for_each_dsi_port(port, intel_dsi->ports) + I915_WRITE(MIPI_MAX_RETURN_PKT_SIZE(port), 8 * 4); + } else { msleep(20); /* XXX */ for_each_dsi_port(port, intel_dsi->ports) dpi_send_cmd(intel_dsi, TURN_ON, DPI_LP_MODE_EN, port);
