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.

The combination of dev_err() and __func__ make most of these log prints
over 100 chars long. Remove the usage of __func__ to clean the kernel
log and as the usage is not necessary to identify the individual log
prints.

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

This patch moves static allocation of snd_soc_card to dynamic allocation,
the reason to do this is to avoid holding up any dangling pointers
in this static structures. And I see no use for having this struct as static
given that the card->name is also populated dynamically from dt.
