       "A collection of small fixes gathered in the last two weeks.
      
        The major changes here are fixes for the recent DPCM regressions found
        on i.MX and Qualcomm platforms and fixes for resource leaks in ASoC
        DAI registrations.
      
        Other than those are mostly device-specific fixes including the usual
        USB- and HD-audio quirks, and a fix for syzkaller case and ID updates
        for new Intel platforms"

      ALSA: usb-audio: Fix OOB access of mixer element list · 220345e9
      Takashi Iwai authored
      The USB-audio mixer code holds a linked list of usb_mixer_elem_list,
      and several operations are performed for each mixer element.  A few of
      them (snd_usb_mixer_notify_id() and snd_usb_mixer_interrupt_v2())
      assume each mixer element being a usb_mixer_elem_info object that is a
      subclass of usb_mixer_elem_list, cast via container_of() and access it
      members.  This may result in an out-of-bound access when a
      non-standard list element has been added, as spotted by syzkaller
      recently.
      
      This patch adds a new field, is_std_info, in usb_mixer_elem_list to
      indicate that the element is the usb_mixer_elem_info type or not, and
      skip the access to such an element if needed.

      erofs: fix partially uninitialized misuse in z_erofs_onlinepage_fixup · 3c597282
      Gao Xiang authored
      Hongyu reported "id != index" in z_erofs_onlinepage_fixup() with
      specific aarch64 environment easily, which wasn't shown before.
      
      After digging into that, I found that high 32 bits of page->private
      was set to 0xaaaaaaaa rather than 0 (due to z_erofs_onlinepage_init
      behavior with specific compiler options). Actually we only use low
      32 bits to keep the page information since page->private is only 4
      bytes on most 32-bit platforms. However z_erofs_onlinepage_fixup()
      uses the upper 32 bits by mistake.
      
      Let's fix it now.

      s390/debug: avoid kernel warning on too large number of pages · 827c4913
      Christian Borntraeger authored
      When specifying insanely large debug buffers a kernel warning is
      printed. The debug code does handle the error gracefully, though.
      Instead of duplicating the check let us silence the warning to
      avoid crashes when panic_on_warn is used.
