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:
(http://coccinelle.lip6.fr/)

// <smpl>

The effect on the layout of the .o files is shown by the following output
of the size command, first before then after the transformation:

This patch can attach automaticlly rt5514 spi DAI with driver name "rt5514"
in the snd_soc_find_dai process. Turn this feature on, we can enable the
voice wake up via rt5514 dsp for RK3399 Gru Boards.

Because we need to support the multiple codecs (MAX98357A/RT5514/DA7219)
on the RK3399 GRU boards, this patch can help us to support these codecs.
