Pull device mapper fixes from Mike Snitzer:
"Five stable fixes:

- Two DM btree bufio buffer leak fixes that resolve reported BUG_ONs
during DM thinp metadata close's dm_bufio_client_destroy().

- A DM thinp range discard fix to handle discarding a partially
mapped range.

- A DM thinp metadata snapshot fix to make sure the btree roots saved
in the metadata snapshot are the most current.

- A DM space map metadata refcounting fix that improves both DM thinp
and DM cache metadata"

dm thin metadata: fix bug when taking a metadata snapshot

When you take a metadata snapshot the btree roots for the mapping and
details tree need to have their reference counts incremented so they
persist for the lifetime of the metadata snap.

The roots being incremented were those currently written in the
superblock, which could possibly be out of date if concurrent IO is
triggering new mappings, breaking of sharing, etc.

Fix this by performing a commit with the metadata lock held while taking
a metadata snapshot.

dm thin metadata: fix bug in dm_thin_remove_range()

dm_btree_remove_leaves() only unmaps a contiguous region so we need a
loop, in __remove_range(), to handle ranges that contain multiple
regions.

A new btree function, dm_btree_lookup_next(), is introduced which is
more efficiently able to skip over regions of the thin device which
aren't mapped. __remove_range() uses dm_btree_lookup_next() for each
iteration of __remove_range()'s loop.

Also, improve description of dm_btree_remove_leaves().

ASoC: Fixes for v4.4

Quite a large batch of fixes have come in since the merge window, mainly
driver specific ones but there's a couple of core ones:

- A fix for DAPM resume on active streams to ensure everything ends up
cleanly in the right state.
- Reset the DAPM cache when freeing widgets to fix a crash on driver
remove and reload.

The PM functions for nau8825 are new code which fix crashes on resume.

Jens' for-4.4/reservations branch because the associated DM changes
required it.

- Revert a dm-multipath change that caused a regression for
unprivledged users (e.g. kvm guests) that issued ioctls when a
multipath device had no available paths.

- Include Christoph's refactoring of DM's ioctl handling and add
support for passing through persistent reservations with DM
multipath.

- All other changes are very simple cleanups"
