[PATCH] drm: bridge: dw-hdmi: Fix overflow workaround for Amlogic Meson GX SoCs

[PATCH] drm: bridge: dw-hdmi: Fix overflow workaround for Amlogic Meson GX SoCs

[Neil Armstrong]

The Amlogic Meson GX SoCs, embedded the v2.01a controller, has been also
identified needing this workaround.
This patch adds the corresponding version to enable a single iteration for
this specific version.

This patch is now present in linux master as commit 9c305eb442f3b371fc722ade827bbf673514123e
Could it be selected for 4.14 ?
The patch has been reworked to apply for 4.17 as indicated in the commit log, but the original patch will apply over 4.14.

Thanks,
Neil

I don't have any "original" patch here, I just tried applying it to
4.16.y and 4.14.y and it did not work.  Can you please provide a working
backport?
