I now tested this version of these four patches too, in the same way as
the previous version from March 5.
kernel: v4.5-rc6 plus
    ALSA: dice: limit to current sampling transfer frequency
    ALSA: dice: limit stream to current sampling transfer frequency.
    ALSA: dice: add MIDI ports according to current number of MIDI substreams
    ALSA: dice: get the number of MBLA data channel at opening PCM substream
    ALSA: dice: purge generating channel cache
    ALSA: dice: ensure phase lock before starting streaming
    ALSA: dice: change notification mask to detect lock status change
    ALSA: dice: old firmware optimization for Dice notification
    ALSA: dice: drop duplex streams synchronization to transfer own time stamps
cherry-picked from tiwai/sound.git, and current 4 patches applied on top.
Host: AMD64, Texas Instruments XIO2213B FireWire adapter.
Audio devices tested:  Focusrite Saffire PRO 24 and PRO 40.
Again no regression with PRO 24 or PRO 40, previously inaccessible higher
channels of the PRO 40 are now accessible (now as devices 0 and 1 on the
respective ALSA card), older muting quirk of the PRO 40 at 88.2/96 kHz still
happens with or without the 9+4 dice patches.
