Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):
https://elixir.bootlin.com/linux/v6.4-rc1/source/Documentation/process/submitting-patches.rst#L597

Subject: Make it concise, like: "Add StarFive JH7110 SoC display bridge
or something".
