The newly added mediatek HDMI driver clashes with an API change
for struct hdmi_codec_ops, causing an 'allmodconfig' build to fail:

drivers/gpu/drm/mediatek/mtk_hdmi.c:1653:15: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
drivers/gpu/drm/mediatek/mtk_hdmi.c:1654:19: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
drivers/gpu/drm/mediatek/mtk_hdmi.c:1655:20: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
drivers/gpu/drm/mediatek/mtk_hdmi.c:1656:18: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
drivers/gpu/drm/mediatek/mtk_hdmi.c:1657:13: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]

This changes the API accordingly for the mediatek driver.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Fixes: 8f83f26891e1 ("drm/mediatek: Add HDMI support")
Fixes: efc9194bcff8 ("ASoC: hdmi-codec: callback function will be called with private data")
---
The new driver is currently part of Dave Airlie's drm-next tree,
while the API change is in Mark Brown's asoc-next tree, so my
fix has to be done on top of both.

I can see two ways out of this:

a) Stephen Rothwell could add my fixup on top of linux-next
   as a merge fix, and the fix gets sent to Linus Torvalds along
   with the second of the two branches

b) efc9194bcff8 gets merged into drm-next along with my change
   in the merge commit. It is currently a standalone patch
   in its own branch in the ASoC tree.

Thanks for sorting this out.

I'll do this today, unless someone does the other.
