       "The most important part in the pull is disablement of the new syscall

        The reason is some people at LWN discussion pointed out dirfd would be
        useful for this path based syscall and Christian Brauner agreed.
      
        Without dirfd it may be indeed problematic for containers. So let's
        just disable the syscall for now when it doesn't have users yet so
        that we have more time to mull over how to best specify the filesystem

      Hans de Goede authored
      Add touchscreen info for the Chuwi Hi10 Pro (CWI529) tablet. This includes
      info for getting the firmware directly from the UEFI, so that the user does
      not need to manually install the firmware in /lib/firmware/silead.
      
      This change will make the touchscreen on these devices work OOTB,
      without requiring any manual setup.

      quota: Disable quotactl_path syscall · 5b9fedb3
      Jan Kara authored
      In commit fa8b9007 ("quota: wire up quotactl_path") we have wired up
      new quotactl_path syscall. However some people in LWN discussion have
      objected that the path based syscall is missing dirfd and flags argument
      which is mostly standard for contemporary path based syscalls. Indeed
      they have a point and after a discussion with Christian Brauner and
      Sascha Hauer I've decided to disable the syscall for now and update its
      API. Since there is no userspace currently using that syscall and it
      hasn't been released in any major release, we should be fine.

      ALSA: intel8x0: Don't update period unless prepared · c1f06161
      Takashi Iwai authored
      The interrupt handler of intel8x0 calls snd_intel8x0_update() whenever
      the hardware sets the corresponding status bit for each stream.  This
      works fine for most cases as long as the hardware behaves properly.
      But when the hardware gives a wrong bit set, this leads to a zero-
      division Oops, and reportedly, this seems what happened on a VM.
      
      For fixing the crash, this patch adds a internal flag indicating that
      the stream is ready to be updated, and check it (as well as the flag
      being in suspended) to ignore such spurious update.
