      I overlooked the issue because when I was working on the said commit,
      only the front audio is tested. Apology for that.
      
      Changing supports_autosuspend in driver is too late for disabling
      autosuspend, because it was already used by USB probe routine, so it can
      break the balance on the following code that depends on
      supports_autosuspend.
      
      Fix it by using usb_disable_autosuspend() helper, and balance the
      suspend count in disconnect callback.

      ALSA: ctxfi: cthw20k2: fix mask on conf to allow 4 bits · 26a9630c
      Colin Ian King authored
      Currently the mask operation on variable conf is just 3 bits so
      the switch statement case value of 8 is unreachable dead code.
      The function daio_mgr_dao_init can be passed a 4 bit value,
      function dao_rsc_init calls it with conf set to:
      
           conf = (desc->msr & 0x7) | (desc->passthru << 3);
      
      so clearly when desc->passthru is set to 1 then conf can be
      at least 8.
      
      Fix this by changing the mask to 0xf.

      ALSA: usb-audio: Allow modifying parameters with succeeding hw_params calls · 5f5e6a3e
      Takashi Iwai authored
      The recent fix for the hw constraints for implicit feedback streams
      via commit e4ea77f8 ("ALSA: usb-audio: Always apply the hw
      constraints for implicit fb sync") added the check of the matching
      endpoints and whether those EPs are already opened.  This is needed
      and correct, per se, even for the normal streams without the implicit
      feedback, as the endpoint setup is exclusive.
      
      However, it's reported that there seem applications that behave in
      unexpected ways to update the hw_params without clearing the previous
      setup via hw_free, and those hit a problem now: then hw_params is
      called with still the previous EP setup kept, hence it's restricted
      with the previous own setup.  Although the obvious fix is to call
      snd_pcm_hw_free() API in the application side, it's a kind of
      unwelcome change.
      
      This patch tries to ease the situation: in the endpoint check, we add
      a couple of more conditions and now skip the endpoint that is being
      used only by the stream in question itself.  That is, in addition to
      the presence check of ep (ep->cur_audiofmt is non-NULL), when the
      following conditions are met, we skip such an ep:
      - ep->opened == 1, and
      - ep->cur_audiofmt == subs->cur_audiofmt.
      
      subs->cur_audiofmt is non-NULL only if it's a re-setup of hw_params,
      and ep->cur_audiofmt points to the currently set up parameters.  So if
      those match, it must be this stream itself.
      
      Fixes: e4ea77f8 ("ALSA: usb-audio: Always apply the hw constraints for implicit fb sync")

      kbuild: make -s option take precedence over V=1 · 22149454
      Masahiro Yamada authored
      'make -s' should be really silent. However, 'make -s V=1' prints noisy
      log messages from some shell scripts.
      
      Of course, such a combination is odd, but the build system needs to do
      the right thing even if a user gives strange input.
      
      If -s is given, KBUILD_VERBOSE should be forced to 0.

      kbuild: fix UNUSED_KSYMS_WHITELIST for Clang LTO · a6aaeb84
      Masahiro Yamada authored
      Commit fbe078d3 ("kbuild: lto: add a default list of used symbols")
      does not work as expected if the .config file has already specified
      CONFIG_UNUSED_KSYMS_WHITELIST="my/own/white/list" before enabling
      CONFIG_LTO_CLANG.
      
      So, the user-supplied whitelist and LTO-specific white list must be
      independent of each other.
      
      I refactored the shell script so CONFIG_MODVERSIONS and CONFIG_CLANG_LTO
      handle whitelists in the same way.

      Pull io_uring thread rewrite from Jens Axboe:
       "This converts the io-wq workers to be forked off the tasks in question
        instead of being kernel threads that assume various bits of the
        original task identity.
      
        This kills > 400 lines of code from io_uring/io-wq, and it's the worst
        part of the code. We've had several bugs in this area, and the worry
        is always that we could be missing some pieces for file types doing
        unusual things (recent /dev/tty example comes to mind, userfaultfd
        reads installing file descriptors is another fun one... - both of
        which need special handling, and I bet it's not the last weird oddity
        we'll find).
      
        With these identical workers, we can have full confidence that we're
        never missing anything. That, in itself, is a huge win. Outside of
        that, it's also more efficient since we're not wasting space and code
        on tracking state, or switching between different states.
      
        I'm sure we're going to find little things to patch up after this
        series, but testing has been pretty thorough, from the usual
        regression suite to production. Any issue that may crop up should be
        manageable.
      
        There's also a nice series of further reductions we can do on top of
        this, but I wanted to get the meat of it out sooner rather than later.
        The general worry here isn't that it's fundamentally broken. Most of
        the little issues we've found over the last week have been related to
        just changes in how thread startup/exit is done, since that's the main
        difference between using kthreads and these kinds of threads. In fact,
        if all goes according to plan, I want to get this into the 5.10 and
        5.11 stable branches as well.
      
        That said, the changes outside of io_uring/io-wq are:
      
         - arch setup, simple one-liner to each arch copy_thread()
           implementation.
      
         - Removal of net and proc restrictions for io_uring, they are no
           longer needed or useful"

      ALSA: usb-audio: Drop bogus dB range in too low level · 21cba9c5
      Takashi Iwai authored
      Some USB audio firmware seem to report broken dB values for the volume
      controls, and this screws up applications like PulseAudio who blindly
      trusts the given data.  For example, Edifier G2000 reports a PCM
      volume from -128dB to -127dB, and this results in barely inaudible
      sound.
      
      This patch adds a sort of sanity check at parsing the dB values in
      USB-audio driver and disables the dB reporting if the range looks
      bogus.  Here, we assume -96dB as the bottom line of the max dB.
      
      Note that, if one can figure out that proper dB range later, it can be
      patched in the mixer maps.
