commit b8dc7d0eea5a7709bb534f1b3ca70d2d7de0b42c introduced
IPA_STATUS_SIZE as a replacement for the size of the removed struct
ipa_status. sizeof(struct ipa_status) was sizeof(__le32[8]), use this
as IPA_STATUS_SIZE.
This is better, however it really isn't done in a way that's
appropriate for a Linux kernel patch.  I will gladly help you
get it right if you have the patience for that.  But I'm not
going to say anything yet--until you say you want me to help
you do this.  If you prefer, I can submit the patch for you.

The reason this is important is your commit is permanent, and
just like code, commit messages are best if kept consistent
and readable.  I also am offering to help you understand so
you avoid any trouble next time you want to send a kernel patch.

Let me know what you prefer.

So here's v3 of the patch, done (I hope) in a way that is more standard
conforming.

Subject: [PATCH] net/ipa: Use correct value for IPA_STATUS_SIZE

IPA_STATUS_SIZE was introduced in commit b8dc7d0eea5a as a replacement
for the size of the removed struct ipa_status which had size
sizeof(__le32[8]). Use this value as IPA_STATUS_SIZE.

This is better, but there are a few more things to do differently.
- When re-submitting a patch, please indicate a (new) version in
   the subject line.  Since you haven't been doing that, it should
   be sufficient to just use "version 2", something like this:
     [PATCH net v2] net: ipa: Use the correct value for IPA_STATUS_SIZE
- Add a "Fixes" tag above your "Signed-off-by:" line:
     Fixes: b8dc7d0eea5a ("net: ipa: stop using sizeof(status)")
- Do not send information above the patch in the e-mail.  An easy
   way to get it right is to use "git send-email".  For example:
     - git format-patch -1
     - Edit 0001-*.patch, adding lines like this below the "From:" line:
	To: davem@davemloft.net
	To: edumazet@google.com
	To: kuba@kernel.org
	To: pabeni@redhat.com
	Cc: elder@kernel.org
	Cc: netdev@vger.kernel.org
	Cc: linux-arm-msm@vger.kernel.org
	Cc: linux-kernel@vger.kernel.org
     - Run this:
         git send-email --dry-run 0001-*.patch
       to try to catch any errors
     - Finally, run this:
         git send-email 0001-*.patch
       to actually send the patch.  This will require a password.

Even if you don't use "git send-email", just let the e-mail
itself indicate the "From:" and "Subject:" lines.  And have
the content of the e-mail be the patch itself.

I hope this helps.
