      This reverts commit ff878b40.
      
      Unfortunately the recent fix seems bringing another regressions with
      PulseAudio / pipewire, at least for Steinberg and MOTU devices.
      
      As a temporary solution, do a straight revert.  The issue for Android
      will be revisited again later by another different fix (if any).

      open: always initialize ownership fields · f52d74b1
      Tetsuo Handa authored
      Beginning of the merge window we introduced the vfs{g,u}id_t types in
      b27c82e1 ("attr: port attribute changes to new types") and changed
      various codepaths over including chown_common().
      
      During that change we forgot to account for the case were the passed
      ownership value is -1. In this case the ownership fields in struct iattr
      aren't initialized but we rely on them being initialized by the time we
      generate the ownership to pass down to the LSMs. All the major LSMs
      don't care about the ownership values at all. Only Tomoyo uses them and
      so it took a while for syzbot to unearth this issue.
      
      Fix this by initializing the ownership fields and do it within the
      retry_deleg block. While notify_change() doesn't alter the ownership
      fields currently we shouldn't rely on it.
      
      Since no kernel has been released with these changes this does not
      needed to be backported to any stable kernels.

      um: fix default console kernel parameter · 782b1f70
      Christian Lamparter authored
      OpenWrt's UML with 5.15 was producing odd errors/warnings during preinit
      part of the early userspace portion:

      |/etc/preinit: line 58: can't open /dev/tty: No such device or address
      |[...] repeated many times
      
      That "/dev/tty" came from the command line (which is automatically
      added if no console= parameter was specified for the uml binary).
      
      The TLDP project tells the following about the /dev/tty:
      <https://tldp.org/HOWTO/Text-Terminal-HOWTO-7.html#ss7.3>
      | /dev/tty stands for the controlling terminal (if any) for the current
      | process.[...]
      | /dev/tty is something like a link to the actually terminal device[..]
      
      The "(if any)" is important here, since it's possible for processes to
      not have a controlling terminal.
      
      I think this was a simple typo and the author wanted tty0 there.

      ALSA: hda/hdmi: Fix the converter reuse for the silent stream · 5f80d6bd
      Jaroslav Kysela authored
      
      
      When the user space pcm stream uses the silent stream converter,
      it is no longer allocated for the silent stream. Clear the appropriate
      flag in the hdmi_pcm_open() function. The silent stream setup may
      be applied in hdmi_pcm_close() (and the error path - open fcn) again.
      
      If the flag is not cleared, the reuse conditions for the silent
      stream converter in hdmi_choose_cvt() may improperly share
      this converter.
