tegra_rt5677_probe() gets a couple of device nodes with of_parse_phandle(),
but there is no release of them.
The patch adds the release to tegra_rt5677_remove() and
to error handling paths in the probe.

Since jack gpios are managed via devres, we don't have to call
snd_jack_free_gpios() at release any longer.

First of all,the address of pdev->dev is assigned to card->dev,then
the function platform_set_drvdata copies the value the variable card
to pdev->dev.driver_data, but when calling snd_soc_register_card,the
function dev_set_drvdata(card->dev, card) will also do the same copy
operation,so i think that the former copy operation can be removed.

Check for snd_soc_ops structures that are only stored in the ops field of a
snd_soc_dai_link structure. This field is declared const, so snd_soc_ops
structures that have this property can be declared as const also.
The semantic patch that makes this change is as follows:

The dapm field of the snd_soc_codec struct will eventually be removed
(replaced with the DAPM context from the component embedded inside the
CODEC). Replace its usage with the card's DAPM context. The idea is that
DAPM is hierarchical and with the card at the root it is possible to access
widgets from other contexts through the card context.
