I borked up this mail. It should have been marked v2 and contain:

Changes since (implicit) v1, sent with Message-Id:
1439798167-21072-1-git-send-email-u.kleine-koenig@xxxxxxxxxxxxxx

 - Use msleep instead of mdelay

But that shouldn't make any difference when you apply the patch, so I
don't resend.
