Dear Igor,
thank you for following my advise. Some more minor suggestions are
inlined but until the maintainers ask for further changes you do not
need to take any further actions.

So here is the formatted version:
Normally when sending patches no introduction or email style formalities
(like greeting and so on) are needed.
If you want to use them put them at the top and separate them from the
patch using
---- 8< ----- >8 ----
so that `git am --scissors` strips the email text off automatically.

SeaMonkey and some Thunderbird versions seem to have a bug deleting a
space before »<«.
But if your email account you sending the message from is the same as
the commit author of the patch you can also delete that line.

Subject: [PATCH] Device list sort function bug
You can copy the text after »Subject: « into the email message subject
line. Then your message automatically has the »PATCH« tag.
Sometimes PowerTOP dies with a Segmentation Fault while generating
the report. Little investigation shown that it dies while sorting
the device list. The problem is that comparison function devlist_sort
is incorrect.
The function should return true if first argument "preceeds" second.
But when strcmp() is used, it can return -1, 0 and 1. So both -1 and 1
values are silently converted to true, which is wrong. It confuses the sort()
function and it crosses boundary of array.

Some comments not meant for the commit message, like what changed in
patch iterations go after the --- line and Git will ignore them.

Just delete the quote next time if you are not citing it in any way [1].
