From: Paulo Zanoni <paulo.r.zanoni at intel.com> - intel_encoder->type is INTEL_OUTPUT_SOMETHING - drm_encoder->encoder_type is DRM_MODE_ENCODER_SOMETHING Here we're using intel_encoder, so compare the oranges against oranges. While at it, rename the variable to "intel_encoder" so we keep our naming standards used everywhere. Luckily this was not a bug because both DRM_MODE_ENCODER_DAC and INTEL_OUTPUT_ANALOG are defined as 1. This is the only case where the drm definition matches the intel definition.
