Sorry, I don't understand your comment.
If we kept component_match_add() in these drivers, then this patch
would not exist, because there wouldn't be any changes to the drivers.

Possibly in the longer term, but at the moment there are drivers where
the match data that is passed does not need any release functionality
eg, data allocated with devm_k*alloc(), or
component_match_add(dev->parent, match, dss_component_compare, dev);
There are some new cases that need converting which have cropped up
during the last merge window, and I expect this to be an on-going
educational point for driver authors, so I'm not too bothered about
capturing all existing cases in this patch.
