Thank you for your feedback and I've updated my email client settings to 
ensure only plain text is sent going forward.

workaround on linux-next

Sorry for any confusion in my previous message. Could you please share 
when we might expect the next non-RFC version of this series, 
specifically for the DSI enablement patch? Alternatively, if there are 
no immediate plans to post an updated version, would it be acceptable 
for us to take it forward and submit the subsequent non-RFC versions of 
the MDSS and DSI enablement device tree patches by adding dependency to 
this https://lore.kernel.org
