For sinks that do not support audio, there is no need to notify audio subsystem of the connection event.
This will make sure that audio routes only to the primary display when connected to such sinks.
Does this need a Fixes tag? Or it's just an optimization patch?
This is an unhandled corner case ( VGA dongle ) for DP audio and will make sure we do not switch audio output from primary to external when connected to a sink which does not support audio. I thought of adding a fixes tag pointing to https://patchwork.freedesktop.org/patch/390236/. But at the same time, thought this can go in as a standlone patch as well. If you think its required, I will add the fixes tag pointing to the base audio patch.
Yeah Fixes is nice so we know what is fixed.
Ok sure, will include it.

g_dp_display is the global dp_display pointer in the dp_display.c file. It does compile.
Oh gross. Can we not use it if dp_display points to it?
Ok sure, will get it from dp_display
