Hi Caesar, Jinkun, Am Dienstag, 8.

The issue behind this is, that Caesar is the sender of the patches and how they stand right now would also be the author, but Jinkun was the first to sign them off, which is normally the line of the author. Please decide who gets to be author of patches 1,3 and 4. If it's Caesar, we'll drop the Signed-off-by or if it's Jinkun we'll change the author. There is no big need to resend the patches, I can adapt authorship if necessary. Thanks Heiko

You can drop the Signed-off-by. --- Thanks, Caesar > There is no big need to resend the patches, I can adapt authorship if > necessary. > > > Thanks > Heiko > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
