Hi Archit & Many thanks.

Benjamin integrated the last 3 patches + its last fix "drm: stm: remove 
"default y" in Kconfig". So you should add CONFIG_DRM_STM=y too.

I take the opportunity to thank you for your great support, I learned so 
much from you and from drm & kernel communities : )

*BIG THANK YOU* to all of you,

Philippe
