Hi,
This patchset is for Linux 4.6-rc2.
ALSA dice driver causes kernel NULL pointer dereference in a case that
no sound card instance is registered and unit is going to be removed.
This is observed when dice-based units are connected to Linux system and
disconnected within 2 seconds, thus it's rare.
Additionally, even if the bug is fixed, the driver dumps warnings for
most dice-based models which supports a pair of isochronous streams.
This can occur regardless of the former bug. Users can see this for
unsupported dice-based models.
This patchset fixes these bugs.

ALSA: dice: fix NULL pointer dereference at remove units when sound
card is not registered

initialized
