[PATCH v4] ASoC: dfbmcs320: make the driver common for other BT modules

DFBM-CS320 is only one of bluetooth modules using CSR bluetooth chips,
we don't want everyone to have a seperate codec driver. anyway, the
feature of Bluetooth SCO is same on all platforms, so this patch
makes the DFBM-CS320 driver become a common BT SCO link driver.

[PATCH] ASoC: wm8994: Handle LRCLK inversion for WM8958 and WM1811A

On WM8958 and WM1811A separate control of the LRCLK inversion bit is
available for the DAC and ADC LRCLKs which for compatibility reasons is
done in a new register bit.

Since writes to each scheme have no effect on parts using the other just
always write to both for simplicity.

module dependency between i915 and snd-hda-intel

Hi Takashi,

Seems kernel building will determine the module loading sequence, this would fix the dependency for i915
and snd-hda-intel.
If we call the i915 module API directly in snd-hda-intel side, kernel building will change the module.dep
accordingly like:
"
kernel/sound/pci/hda/snd-hda-intel.ko: kernel/drivers/gpu/drm/i915/i915.ko
kernel/drivers/gpu/dr     m/drm_kms_helper.ko kernel/drivers/gpu/drm/drm.ko
kernel/drivers/i2c/algos/i2c-algo-bit.ko kerne     l/drivers/acpi/video.ko
kernel/sound/pci/hda/snd-hda-codec.ko kernel/sound/core/snd-hwdep.ko ker    
nel/sound/core/snd-pcm.ko kernel/sound/core/snd-timer.ko kernel/sound/core/snd.ko
kernel/sound/s     oundcore.ko kernel/sound/core/snd-page-alloc.ko
"
So snd-hda-intel will wait for i915 loading. Even I added i915 into blacklist.conf, it will force load i915.ko.

So I think the only bad case is no i915 module built-in, that would cause haswell hda initialize fail, and the
patch would output error message.

thanks
