      ALSA: usb-audio: Add support for Pioneer DJM-750 · b952ac76
      Olivia Mackintosh authored 
      This adds the Pioneer DJ DJM-750 to the quirks table and ensures
skip_pioneer_sync_ep() is (also) called: this device uses the vendor
ID of 0x08e4 (I'm not sure why they use multiple vendor IDs but many
just like to be awkward it seems).

Playback on all 8 channels works. I'll likely keep this working in the
future and submit futher patches and improvements as necessary.

      ALSA: usb-audio: Avoid implicit feedback on Pioneer devices · 532a208a
      Takashi Iwai authored 
      For addressing the regression on Pioneer devices, we recently
corrected the quirk code to enable the implicit feedback mode on those
devices properly.  However, the devices still showed problems with the
full duplex operations with JACK, and after debug sessions, we figured
out that the older kernels that had worked with JACK also didn't use
the implicit feedback mode at all although they had the quirk code to
enable it; instead, the old code worked just to skip the normal sync
endpoint setup that would have been detected without it.  IOW, what
broke without the implicit-fb quirk in the past was the application of
the normal sync endpoint that is actually the capture data endpoint on
these devices.

This patch covers the overseen piece: it modifies the quirk code again
not to enable the implicit feedback mode but just to make the driver
skipping the sync endpoint detection.  This made the driver working
with JACK full-duplex mode again.

Still it's not quite clear why the implicit feedback doesn't work on
those devices yet; maybe it's about some issues in the URB setup.  But
at least, with this patch, the driver should work in the level of the
older kernels again.

      ALSA: usb-audio: Set sample rate for all sharing EPs on UAC1 · 3784d449
      Takashi Iwai authored 
      The UAC2/3 sample rate setup is based on the clock node, which is
usually shared in the interface, and can't be re-setup without
deselecting the interface once, and that's how the current code
behaves.  OTOH, the sample rate setup of UAC1 is per endpoint, hence
we basically need to call for each endpoint usage even if those share
the same interface.

This patch fixes the behavior of UAC1 to call always
snd_usb_init_sample_rate() in snd_usb_endpoint_configure().

      ALSA: usb-audio: Fix UAC1 rate setup for secondary endpoints · 87cb9af9
      Takashi Iwai authored 
      The current sample rate setup function for UAC1 assumes only the first
endpoint retrieved from the interface:altset pair, but the rate set up
may be needed also for the secondary endpoint.  Also, retrieving the
endpoint number from the interface descriptor is redundant; we have
already the target endpoint in the given audioformat object.

This patch simplifies the code and corrects the target endpoint as
described in the above.  It simply refers to fmt->endpoint directly.

Also, this patch drops the pioneer_djm_set_format_quirk() that is
caleld from snd_usb_set_format_quirk(); this function does the sample
rate setup but for the capture endpoint (0x82), and that's exactly
what the change above fixes.

      ALSA: hda/via: Fix runtime PM for Clevo W35xSS · 4bfd6247
      Takashi Iwai authored 
      Clevo W35xSS_370SS with VIA codec has had the runtime PM problem that
looses the power state of some nodes after the runtime resume.  This
was worked around by disabling the default runtime PM via a denylist
entry.  Since 5.10.x made the runtime PM applied (casually) even
though it's disabled in the denylist, this problem was revisited.  The
result was that disabling power_save_node feature suffices for the
runtime PM problem.

This patch implements the disablement of power_save_node feature in
VIA codec for the device.  It also drops the former denylist entry,
too, as the runtime PM should work in the codec side properly now.

Fixes: b529ef24 ("ALSA: hda: Add Clevo W35xSS_370SS to the power_save blacklist")
