      ALSA: usb-audio: Fix potential use-after-free of streams · ff58bbc7
      Takashi Iwai authored
      With the recent full-duplex support of implicit feedback streams, an
      endpoint can be still running after closing the capture stream as long
      as the playback stream with the sync-endpoint is running.  In such a
      state, the URBs are still be handled and they may call retire_data_urb
      callback, which tries to transfer the data from the PCM buffer.  Since
      the PCM stream gets closed, this may lead to use-after-free.
      
      This patch adds the proper clearance of the callback at stopping the
      capture stream for addressing the possible UAF above.
      
      Fixes: 10ce77e4 ("ALSA: usb-audio: Add duplex sound support for USB devices using implicit feedback")

      ALSA: usb-audio: Add Pioneer DJ DJM-900NXS2 support · 7fccfecf
      Dmitry Panchenko authored
      
      
      Pioneer DJ DJM-900NXS2 is a widely used DJ mixer with 2 audio USB
      interfaces. Both have a MIDI controller, 10 playback and 12 capture
      channels. Audio endpoints are vendor-specific and 3 files need to be
      patched. All playback and capture channels work fine with all supported
      sample rates (44.1k, 48k, 96k). Patches are attached.

      Merge tag 'asoc-v5.8' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
      
      ASoC: Updates for v5.8
      
      This has been another very active release with a bunch of new drivers,
      lots of fixes everywhere and continued core improvements from
      Morimoto-san:
      
       - Lots of core cleanups and refactorings from Morimoto-san, factoring
         out common operations and making the card abstraction more solid.
       - Continued work on cleaning up and improving the Intel drivers, along
         with some new platform support for them.
       - Fixes to make the Marvell SSPA driver work upstream.
       - Support for AMD Renoir ACP, Dialog DA7212, Freescale EASRC and
         i.MX8M, Intel Elkhard Lake, Maxim MAX98390, Nuvoton NAU8812 and
         NAU8814 and Realtek RT1016.
