Do not use "This commit/patch". https://elixir.bootlin.com/linux/v5.17.1/source/Documentation/process/submitting-patches.rst#L95 Subject: drop second/last, redundant "bindings for".

Why do you split the binding? It really looks unnecessary.

Full, real path please, so it could be validated with tools. Best regards, Krzysztof
