Additional to Wolfgang's comments:
- Your mailer has wrapped the commit text above. Please you shorter
lines next time
- The subject line is still way too long. Please try to find a short
one line subject for the patch like:
"[PATCH] ppc4xx: Fix Sequoia EBC configuration for new board revision"
Thanks.
Best regards,
Stefan
