[Intel-gfx] [PATCH] dim: Add helper command to generate Fixes: lines

[Daniel Vetter]

Unfortunately a simple git alias doesn't work since the linux kernel
wants a sha1 shortened to 12 characters, and the git commit
prettifying can't do that with e.g. %12h. sed to the rescue.

I'm using this when editing commit messages after applying (:read !dim
fixes sha1 in vim).
