If so, (and the troublesome problem with the IPU crtcs is now gone) we can modify the core component code such that it does this: if (c->master && c->master != master) continue; if (compare(c->dev, compare_data)) { if (!c->master) component_attach_master(master, c); ret = 0; break; } which will mean that you don't need to build this list anymore to track what will be added - though I'd like to think a little more about that before making that change. Please confirm whether this will eliminate your list generation.
