A card is fully routed if the DAPM route table describes all connections on the board. When a card is fully routed, some operations can be automated by the ASoC core. The first, and currently only, such operation is described below, and implemented by this patch. Codecs often have a large number of external pins, and not all of these pins will be connected on all board designs. Some machine drivers therefore call snd_soc_dapm_nc_pin() for all the unused pins, in order to tell the ASoC core never to activate them. However, when a card is fully routed, the information needed to derive the set of unused pins is present in card->dapm_routes. In this case, have the ASoC core automatically call snd_soc_dapm_nc_pin() for each unused codec pin. This has been tested with soc/tegra/tegra_wm8903.c and soc/tegra/trimslice.c.
