RE: [RFC 0/6] mmc: Field Firmware Update

[Avi Shchislowski <Avi.Shchislowski@sandisk.com>]

Hi Holger,

Thank you for resubmitting the FFU patches again.
We did couple of fixes since our last submission (in [RFC 6/6]), so we will post them soon.
Also, we would like to leave the original "signed-off-by" names in your FFU patch commits.
Could you please add the original:
Signed-off-by: Avi Shchislowski <avi.shchislowski@sandisk.com>
Signed-off-by: Alex Lemberg <Alex.Lemberg@sandisk.com>

Thanks,
Avi & Alex
