A call of pci_iounmap() call without CONFIG_PCI leads to a build error
on some architectures.  We tried to address this and add a check of
IS_ENABLED(CONFIG_PCI), but this still doesn't seem enough for sh.
Ideally we should fix it globally, it's really a corner case, so let's
paper over it with a simpler ifdef.

This patch adds the T+A VID to the generic check in order to enable
native DSD support for T+A devices. This works with the new T+A USB
DAC model SD3100HV and will also work with future devices which
support the XMOS/Thesycon style DSD format.

In the current code, the codec registration may happen both at the
codec bind time and the end of the controller probe time.  In a rare
occasion, they race with each other, leading to Oops due to the still
uninitialized card device.

This patch introduces a simple flag to prevent the codec registration
at the codec bind time as long as the controller probe is going on.
The controller probe invokes snd_card_register() that does the whole
registration task, and we don't need to register each piece
beforehand.

Replace the open-codes in many places with a new common helper for
performing the same thing: referring to the primary headphone pin.

This eventually fixes the potentially missing headphone pin on some
weird devices, too.

On the System76 Darter Pro (darp5), there is a headset microphone
input attached to 0x1a that does not have a jack detect.  In order to
get it working, the pin configuration needs to be set correctly, and
the ALC269_FIXUP_HEADSET_MODE_NO_HP_MIC fixup needs to be applied.
This is similar to the MIC_NO_PRESENCE fixups for some Dell laptops,
except we have a separate microphone jack that is already configured
correctly.

Fix hp_pin always no value.

[More notes on the changes:

 The hp_pin value that is referred in alc294_hp_init() is always zero
 at the moment the function gets called, hence this is actually
 useless as in the current code.

 And, this kind of init sequence should be called from the codec init
 callback, instead of the parser function.  So, the first fix in this
 patch to move the call call into its own init_hook.

 OTOH, this function is needed to be called only once after the boot,
 and it'd take too long for invoking at each resume (where the init
 callback gets called).  So we add a new flag and invoke this only
 once as an additional fix.

 The one case is still not covered, though: S4 resume.  But this
 change itself won't lead to any regression in that regard, so we
 leave S4 issue as is for now and fix it later.  -- tiwai ]

When the trigger=off is passed for a PCM OSS stream, it sets the
start_threshold of the given substream to the boundary size, so that
it won't be automatically started.  This can be problematic for a
capture stream, unfortunately, as detected by syzkaller.  The scenario
is like the following:

- In __snd_pcm_lib_xfer() that is invoked from snd_pcm_oss_read()
  loop, we have a check whether the stream was already started or the
  stream can be auto-started.
- The function at this check returns 0 with trigger=off since we
  explicitly disable the auto-start.
- The loop continues and repeats calling __snd_pcm_lib_xfer() tightly,
  which may lead to an RCU stall.

This patch fixes the bug by simply allowing the wait for non-started
stream in the case of OSS capture.  For native usages, it's supposed
to be done by the caller side (which is user-space), hence it returns
zero like before.

(In theory, __snd_pcm_lib_xfer() could wait even for the native API
 usage cases, too; but I'd like to stay in a safer side for not
 breaking the existing stuff for now.)
