Hmm.. Anyway I have to resend the cam_enc_4xx board port, as now the new
SPL Framework is in mainline, and my post used the old one. Also
I added in the meantime USB support for it, for which I needed this patch.
But actually I am wating for a new HW, so I can't test it ... and then
I post this patchset again with this patch in it! Can I add then your
"Acked-by" for this patch?

Thanks
Heiko
