The subject prefix should be "drm/i915/psr: ". Please try git log on the
file to see what is commonly used.

The subject should say what's being done. "Replace define function" is
way too generic to be useful. Even "Prefer DEFINE_DEBUGFS_ATTRIBUTE" is
better.

Finally, the commit message itself should say *why*. Why are we
replacing DEFINE_SIMPLE_ATTRIBUTE with DEFINE_DEBUGFS_ATTRIBUTE?

BR,
Jani.
