The largest infoframe we create is the DRM (Dynamic Range Mastering)

With HDMI_MAX_INFOFRAME_SIZE set to 29 bytes, as it is now, we
allocate too little space to pack a DRM infoframe in
write_device_infoframe(), leading to an ENOSPC return from
hdmi_infoframe_pack(), and never calling the connector's
write_infoframe() vfunc.

Applied to misc/kernel.git (drm-misc-fixes).

Thanks!
