Hi Philippe,

The pixel clock gets enabled early during init, since it's required in order to read registers. This pixel clock must be disabled if errors during this init phase.
This patch was pulled in to drm-misc-next, but it lacks your Sign-off. It looks like the Ack and the Sign-off got accidentally mixed up
Hi Archit, This patch is from Eric that is why I put his "signed-off-by" and I "acked" it to confirm that the patch is fine to me :-)
Nevertheless, as I am the patch "author" in the git tree, I confirm with my my below signed-off-by:
Signed-off-by: Philippe Cornu philippe.cornu@st.com
Many thanks Philippe :-)
Can you please reply to this mail with your "Signed-off-by" so that we have proof of it on dri-devel?
Thanks, Archit
