      ALSA: hdspm - prevent reading unitialized stack memory · 4ab69a2b
      Adrian Knoth authored
      Original patch by Dan Rosenberg <drosenberg@vsecurity.com> under commit
      e68d3b31. I'm copying his text here:
      
      The SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl in hdspm.c allow unprivileged
      users to read uninitialized kernel stack memory, because several fields
      of the hdspm_config struct declared on the stack are not altered
      or zeroed before being copied back to the user.  This patch takes care
      of it.

      ALSA: hdspm - Remove input selector on MADIface · f6ea805f
      Adrian Knoth authored
      In contrast to the RME MADI card, coax/optical selection on the MADIface
      is done via a physical switch located at the breakout box. Obviously,
      the driver cannot switch ports in software.

      ALSA: hdspm - Fix DS/QS output channel mappings on RME MADI/MADIface · 01e96078
      Adrian Knoth authored
      Caused by two typos, no output channel mappings were assigned for
      MADI/MADIface at double/quad speed.
      
      The channel mapping is indeed identical to the single speed mapping, the
      cards will simply use the first N channels.

      ALSA: hdspm - Restrict channel count on RME AES/AES32 · 88fabbfc
      Adrian Knoth authored
      Without calling an appropriate rule, AES/AES32 cards would announce a
      theoretical channel count of 64 (HDSPM_MAX_CHANNELS), leading to the
      already known bug:

      We already have all the right values in place, we simply have to inform
      the upper layers about this restriction.
      
      Note that snd_hdspm_hw_rule_rate_out_channels and
      snd_hdspm_hw_rule_rate_in_channels must not be called on AES32, because
      the channel count is always 16, no matter of the samplerate in use.

      ALSA: hdspm - Fix buffer handling on RME MADI/MADIface/AES(32) · 483cee77
      Adrian Knoth authored
      Only RayDAT and AIO provide sane buffer pointers that can be used with
      HDSPM_BufferPositionMask, on all other cards, this would result in a
      wrong HW pointer leading to xruns and these messages:

      ALSA: hpdsm - RME AES(32): Fix missing channel mappings · 432d2500
      Adrian Knoth authored
      On RME AES and AES(32), none of the required information
      (max_channels_in, max_channels_out, channel mappings, port names) was
      set, leading to the BUG below.
      
      This patch adds the missing bits, thus fixing the bug.
