      ALSA: compress: Fix stop handling on compressed capture streams · 4f2ab5e1
      Charles Keepax authored 
      It is normal user behaviour to start, stop, then start a stream
again without closing it. Currently this works for compressed
playback streams but not capture ones.

The states on a compressed capture stream go directly from OPEN to
PREPARED, unlike a playback stream which moves to SETUP and waits
for a write of data before moving to PREPARED. Currently however,
when a stop is sent the state is set to SETUP for both types of
streams. This leaves a capture stream in the situation where a new
start can't be sent as that requires the state to be PREPARED and
a new set_params can't be sent as that requires the state to be
OPEN. The only option being to close the stream, and then reopen.

Correct this issues by allowing snd_compr_drain_notify to set the
state depending on the stream direction, as we already do in
set_params.

Fixes: 49bb6402 ("ALSA: compress_core: Add support for capture streams")

      virtio: drop internal struct from UAPI · 9c0644ee
      Michael S. Tsirkin authored 
      There's no reason to expose struct vring_packed in UAPI - if we do we
won't be able to change or drop it, and it's not part of any interface.

Let's move it to virtio_ring.c

      ALSA: usb-audio: Add support for new T+A USB DAC · 3bff2407
      Udo Eberhardt authored 
      This patch adds the T+A VID to the generic check in order to enable
native DSD support for T+A devices. This works with the new T+A USB
DAC model SD3100HV and will also work with future devices which
support the XMOS/Thesycon style DSD format.

      efi/arm64: Fix debugfs crash by adding a terminator for ptdump marker · 74c953ca
      Qian Cai authored 
      When reading 'efi_page_tables' debugfs triggers an out-of-bounds access here:

  arch/arm64/mm/dump.c: 282
  if (addr >= st->marker[1].start_address) {

called from:

  arch/arm64/mm/dump.c: 331
  note_page(st, addr, 2, pud_val(pud));

because st->marker++ is is called after "UEFI runtime end" which is the
last element in addr_marker[]. Therefore, add a terminator like the one
for kernel_page_tables, so it can be skipped to print out non-existent
markers.

Here's the KASAN bug report:

cause confusion.

Make the user prompt more specific. Match the config symbol name.
