On Linux 5.9-rc1 I get the following warning with apq8016-sbc:

This warning was introduced in
commit 81033c6b58 ("ALSA: core: Warn on empty module").
It looks like we are supposed to set card->owner to THIS_MODULE.
Fix this for all the qcom ASoC drivers.

commit 3caf11fa88 ("ASoC: qcom: storm: don't select unnecessary
Platform")
Current ALSA SoC avoid to add duplicate component to rtd,
and this driver was selecting CPU component as Platform component.
Thus, above patch removed Platform settings from this driver,
because it assumed these are same component.
But, some CPU driver is using generic DMAEngine, in such case, both
CPU component and Platform component will have same of_node/name.
In other words, there are some components which are different but
have same of_node/name.
In such case, Card driver definitely need to select Platform even
though it is same as CPU.
It is depends on CPU driver, but is difficult to know it from Card driver.
This patch reverts above patch.

ALSA SoC is now supporting "no Platform". Sound card doesn't need to
select "CPU component" as "Platform" anymore if it doesn't need
special Platform.
This patch removes such settings.

ASoC is now supporting modern style dai_link
(= snd_soc_dai_link_component) for CPU/Codec/Platform.
This patch switches to use it.

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:

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.
