Please no, don't do this, see the email archives of this list for why I
don't like this type of change (it forces you do have to remember rules
when looking at the code in the future.)

I wish checkpatch would not report this type of issue anymore...

[PATCH] staging: octeon: remove unnecessary parentheses

[Dorine Tipo]

This patch addresses the unnecessary issue reported by checkpatch.
The subject line has been revised to be more concise and less detailed,
as suggested in the patch feedback.

Changes made:
- Removed unnecessary parentheses around 'interface < 2'.

The parentheses around interface < 2 are not necessary because
the < operator has a higher precedence than the && operator.
In this context, removing these parentheses doesn't change the order of
evaluation or the logic of the code and improves readability

This revision information is supposed to be underneath the ---.  It will
be meaningless to anyone who looks at this patch in the future, because
they won't be seeing the old versions.

Since this is not the first version of this patch, there should be v2 v3
or v4 etc in the subject line after the word PATCH.  Please see the first
patch tutorial in the section Revising your patches

This is a fine explanation, although a bit verbose.  Try to express the
whole thing in 1 or 2 sentences.

This patch is working on the same code as the previous one, but there is
no indication that it is anything other than the first version.

This is quite backwards.  Above the line you should provide all of the
information that will be useful to people in the future, and thus should
be recorded in the git tree.

Below the line, you should indicate what has changed since the previous
version.  This should contain the entire history of the evolution of the
patch, as illustrated in the Revising your patches section of the furst
patch tutorial.

There is still the case that this patch is a revision of a previous one,
but there is no [PATCH v2] in the subject line.  Theer have been a lot of
versions of this patch, so I don't know which number this one would be,
but at least if there were a v2, one would know that the v2 one is more
recent than all of the others.
