Hi Rob,

After merging the drm-msm tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/gpu/drm/msm/hdmi/hdmi.c:523:15: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .hw_params = msm_hdmi_audio_hw_params,
               ^
drivers/gpu/drm/msm/hdmi/hdmi.c:523:15: note: (near initialization for 'msm_hdmi_audio_codec_ops.hw_params')
drivers/gpu/drm/msm/hdmi/hdmi.c:524:20: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .audio_shutdown = msm_hdmi_audio_shutdown,
                    ^
drivers/gpu/drm/msm/hdmi/hdmi.c:524:20: note: (near initialization for 'msm_hdmi_audio_codec_ops.audio_shutdown')

Caused by commit

  bf714255fed7 ("drm: msm: Add ASoC generic hdmi audio codec support.")

interacting with commit

  efc9194bcff8 ("ASoC: hdmi-codec: callback function will be called with private data")

from the sound-asoc (and drm) trees.

I have added this merge fix patch for today (dave will need something
like this when he merges your tree):
