Subject: drm/i915: Add DRM Infoframe handling for BYT/CHT
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c0560fab6d3798cb4a54529cdce0e91a64e978fb;p=linux.git

drm/i915: Add DRM Infoframe handling for BYT/CHT

BYT/CHT doesn't support DRM Infoframe. This caused
a WARN_ON due to a missing CASE while executing
intel_hdmi_infoframes_enabled function. This patch
fixes the same.
