ALSA: control: add support for ENUMERATED user space controls

Handling of user control elements was implemented for all types except
ENUMERATED.  This type will be needed for the device-specific mixers of
upcoming FireWire drivers.

ALSA: control: remove compilation warning on 32-bit

This was introduced by 'ALSA: control: add support for ENUMERATED user
space controls' which adds a u64 variable that gets cast to a pointer:

sound/core/control.c: In function 'snd_ctl_elem_init_enum_names':
sound/core/control.c:1089: warning: cast to pointer from integer of different size

Cast to uintptr_t before casting to pointer to avoid the warning.

ALSA: hwdep: silence integer overflow warning

Smatch complains that if device is INT_MAX then device + 1 can
overflow.  It just means we would have an annoying loop while we
check all the devices from -2147483648 to SNDRV_MINOR_HWDEPS.

ALSA: oss-mixer - use strlcpy() instead strcpy()

This is mostly a static checker fix more than anything else.  We're
copying from a 64 char buffer into a 44 char buffer.

The 64 character buffer is str[] in snd_mixer_oss_build_test_all().
The call tree is:
	snd_mixer_oss_build_test_all()
	-> snd_mixer_oss_build_test()
	   -> snd_mixer_oss_build_test().

We never actually do fill str[] buffer all the way to 64 characters.
The longest string is:
	sprintf(str, "%s Playback Switch", ptr->name);
ptr->name is a 32 character buffer so 32 plus 16 characters for
" Playback Switch" still puts us over the 44 limit from "id.name".

Most likely ptr->name never gets filled to the limit, but we can't
really change the size of that buffer so lets just use strlcpy() here
and be safe.

ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link()

GFP_ATOMIC is used in snd_pcm_link() just because the kmalloc is
called inside a lock.  Since this function isn't too critical for
speed and is rarely called in practice, better to allocate the chunk
at first before spinlock and free it in error paths, so that
GFP_KERNEL can be used.

ASoC: msm: Fix delay in switching from WFD session

- When a running WFD session is paused/disconnected, there is
  a delay of about 10-15 seconds in switching audio from WFD
  sink to target.
- pcm_write is blocked because pausing/disconnecting the WFD
  session closes the backend DAI before a new link is established.
- Avoid closing afe if front end PCM session is still active.
