This warning results because the number of items in "enum rtw_c2h_event",

The fallback to 32-bit DMA mask is rather odd:
if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) &&
!dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) {
*using_dac = true;
} else {
err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32));
if (err) {
err = dma_set_coherent_mask(&pdev->dev,
DMA_BIT_MASK(32));
if (err)
goto release_regions;
}
This means we only try and set the coherent DMA mask if we failed to
set a 32-bit DMA mask, and only if both fail do we fail the driver.
Adjust this so that if either setting fails, we fail the driver - and
thereby end up properly setting both the DMA mask and the coherent
DMA mask in the fallback case.

It needs one regmap_filed for one register access.
OTOH, there is multi port device which
has many same registers in the market.
The difference for each register access is
only its address offset.

ASoC sound driver requires CPU/CODEC drivers for probing,
and each CPU/CODEC has some DAI on it.
Then, "dai name matching" have been used to identify
CPU-CODEC DAI pair on ASoC.
But, the "dai port number matching" is now required from DeviceTree.
The solution of this issue is to replace
the dai port number into dai name.
Now, CPU/CODEC are based on struct snd_soc_component,
and it can care above as common issue.
This patch adds .of_xlate_dai_name callback interface
on struct snd_soc_component_driver,
and snd_soc_of_get_dai_name() which is using .of_xlate_dai_name.
Then, #sound-dai-cells which enables DAI specifier is required
on CPU/CODEC device tree properties.

And now, it will be used from codec also.

Many drivers that use bitbang library have a leak on probe error paths.
This is because once a spi_master_get() call succeeds, we need an additional
spi_master_put() call to free the memory.
Fix this issue by moving the code taking a reference to master to
spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on
success. With this change, the caller is responsible for calling
spi_bitbang_stop() to decrement the reference and spi_master_put() as
counterpart of spi_alloc_master() to prevent a memory leak.
So now we have below patten for drivers using bitbang library:
probe:
spi_alloc_master -> Init reference count to 1
spi_bitbang_start -> Increment reference count
remove:
spi_bitbang_stop -> Decrement reference count
spi_master_put -> Decrement reference count (reference count reaches 0)
Fixup all users accordingly.

probing has completed.
