Please put a shorter version of your commit message in the patch subject
- "[PATCH] Drivers : edac : checkpatch.pl clean up" is not very telling.

Ironically, if you run your patch through checkpatch, it will tell you so too:

WARNING: A patch subject line should describe the change not the tool that found it
#6: 
Subject: [PATCH] Drivers : edac : checkpatch.pl clean up

which means, after you create a patch, run it through checkpatch too.

Also, the subject format should be:

"EDAC, i82860: ..."

Also, the tense in the commit message should not be past: "Fix 'no
assignment ... and remove ...".

No need for the newline.

There's an unnecessary newline in i82860_init_one() too, you can remove
that one too.

	if (!mci)

Finally, do not linger too long fixing checkpatch issues but try to fix
some real bugs. Enough of those in the kernel :-)

Thanks.
