I've added them here. It seems like we'd at least need an Ack by those guys since this modified the msm/Kconfig...

I've added them here. It seems like > we'd at least need an Ack by those guys since this modified the > msm/Kconfig... You are right. The fix originally only touched drivers/gpu/drm/display/Kconfig and I forgot to update the maintainers list for v2 when drivers/gpu/drm/msm/Kconfig had to be modified as well. Thank you for noticing and getting the right people involved, this clearly made a difference :-) > FWIW I haven't spent massive time studying this, but what you have > here looks reasonable.
