This is not the correct way to submit patches for inclusion in the stable kernel tree. Please read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly.

7 bytes of sha1 isn't enough. You can set core.abbrev to 12 or upgrade to a version of git from this decade to get that automatically.
