ALSA timer instance object has a couple of linked lists and they are
unlinked unconditionally at snd_timer_stop().  Meanwhile
snd_timer_interrupt() unlinks it, but it calls list_del() which leaves
the element list itself unchanged.  This ends up with unlinking twice,
and it was caught by syzkaller fuzzer.

The fix is to use list_del_init() variant properly there, too.

The commit [da6d2769: ALSA: usb-audio: Add resume support for

the missing shift at writing.  This patch addresses it.

Currently the info in /proc/interrupts doesn't allow to figure out which
interrupt belongs to which card (HDMI, PCH, ..).
Therefore add card details to the interrupt description.
With the patch the info in /proc/interrupts looks like this:

PCI-MSI 442368-edge      snd_hda_intel:card1
PCI-MSI 49152-edge      snd_hda_intel:card0

NOTE: this patch adds the new irq_descr field snd_card struct that is
filled automatically at a card object creation.  This can be used
generically for other drivers as well.  The changes for others will
follow later -- tiwai

ALSA sequencer code has an open race between the timer setup ioctl and
the close of the client.  This was triggered by syzkaller fuzzer, and
a use-after-free was caught there as a result.

This patch papers over it by adding a proper queue->timer_mutex lock
around the timer-related calls in the relevant code path.

ALSA PCM may still have a leftover instance after disconnection and
it delays its release.  The problem is that the PCM close code path of
USB-audio driver has a call of snd_usb_autosuspend().  This involves
with the call of usb_autopm_put_interface() and it may lead to a
kernel Oops due to the NULL object like:

Merge tag 'asoc-v4.4-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

ASoC: Last updates for v4.5

A bunch more updates for v4.5, mainly driver work:

 - More topology API enhancements from Mengdong Lin working towards
   making everything more component based and being able to specify PCM
   links via topology.
 - Large sets driver updates from Cirrus, Intel (mainly more Skylake
   support) and Renesas.
 - New driver for AMD ACP
 - Rename PCM1792a driver to be generic pcm179x

ASoC: Updates for v4.5

This is quite a busy release on the driver front with a lot of new
drivers being added but comparatively quiet on the core side with only
one big change going in and that a fairly straightforward refactoring.

 - Conversion of the array of DAI links to a list by Mengdong Lin,
   supporting dynamically adding and removing DAI links.
 - Some more fixes for the topology code, though it is still not final
   and ready for enabling in production.  We really need to get to the
   point where that can be done.
 - A pile of changes for Intel SkyLake drivers which hopefully deliver
   some useful initial functionality for systems with this chipset,
   though there is more work still to come.
 - New drivers for a number of Imagination Technologies IPs.
 - Lots of new features and cleanups for the Renesas drivers.
 - ANC support for WM5110.
 - New driver for Atmel class D speaker drivers.
 - New drivers for Cirrus CS47L24 and WM1831.
 - New driver for Dialog DA7128.
 - New drivers for Realtek RT5659 and RT56156.
 - New driver for Rockchip RK3036.
 - New driver for TI PC3168A

aux_dev is mainly used by the machine driver to specify analog devices,
which are registered as codecs. Making it more like a generic component
can help the machine driver to use it to specify any component with
topology info by name.

Details:
- Remove the stub 'rtd_aux' array from the soc card.
- Add a list 'aux_comp_list' to store the components of aux_devs.
  And add a list head 'list_aux' to struct snd_soc_component, for adding
  such components to the above list.
- Add a 'init' ops to a component for machine specific init.
  soc_bind_aux_dev() will set it to be aux_dev's init. And it will be
  called when probing the component.
- soc_bind_aux_dev() will also search components by name of an aux_dev,
  since it may not be a codec.
- Move probing of aux_devs before checking new DAI links brought by
  topology.
- Move removal of aux_devs later than removal of links. Because topology
  of aux components may register DAIs and the DAI drivers will go with
  removal of the aux components, we want soc_remove_link_dais() to remove
  the DAIs at first.
