ASoC: Fixes for v4.5
This is far too big a set of fixes for this late in the release cycle
but the overwhelming bulk is essentially the same simple fix from
Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace
interface where drivers were accessing things using the wrong element in
a union which worked OK on 32 bit platforms as the correct element
happened to be aligned the same way but with 64 bit platforms ABIs are
different and the two members of the union are laid out in different
places. They aren't all tagged to stable since some of these chips have
vanishingly little chance of being used in 64 bit systems.
The other changes are:
- A fix for Qualcomm devices to work on big endian systems. The
original change is actually correct but triggered a bug in regmap
which is too invasive to fix for this cycle and can be worked around
by just letting regmap pick the default.
- A fix for the Samsung I2S driver locking which wasn't using IRQ safe
spinlocks when it needed to.
- A fix for the new Intel Sky Lake driver forgetting that C pointer
arithmetic takes the type of the pointer into consideration.
- A revert of a change to the FSL SSI driver that broke some systems.
- A fix for the cleanup path of the wm9713 driver.
- A fix for some incorrect register definitions in the ADAU17x1 driver
that caused misclocking in some configurations.
- A fix for the tracepoints for jack detection to avoid using an
internal field of the core jack structure which is no longer present
in all configurations.
- A fix for another of the new Intel drivers which tried to write to a
string literal.

BIOS vendors typically list multiple audio codecs in the DSDT

tracing: Do not have 'comm' filter override event 'comm' field
Commit
9f61668073a8d "tracing: Allow triggers to filter for CPU ids and
process names" added a 'comm' filter that will filter events based on the
current tasks struct 'comm'. But this now hides the ability to filter events
that have a 'comm' field too. For example, sched_migrate_task trace event.
That has a 'comm' field of the task to be migrated.
echo 'comm == "bash"' > events/sched_migrate_task/filter
will now filter all sched_migrate_task events for tasks named "bash" that
migrates other tasks (in interrupt context), instead of seeing when "bash"
itself gets migrated.
This fix requires a couple of changes.
1) Change the look up order for filter predicates to look at the events
fields before looking at the generic filters.
2) Instead of basing the filter function off of the "comm" name, have the
generic "comm" filter have its own filter_type (FILTER_COMM). Test
against the type instead of the name to assign the filter function.
3) Add a new "COMM" filter that works just like "comm" but will filter based
on the current task, even if the trace event contains a "comm" field.
Do the same for "cpu" field, adding a FILTER_CPU and a filter "CPU".

Btrfs: fix loading of orphan roots leading to BUG_ON
When looking for orphan roots during mount we can end up hitting a
BUG_ON() (at root-item.c:btrfs_find_orphan_roots()) if a log tree is
replayed and qgroups are enabled. This is because after a log tree is
replayed, a transaction commit is made, which triggers qgroup extent
accounting which in turn does backref walking which ends up reading and
inserting all roots in the radix tree fs_info->fs_root_radix, including
orphan roots (deleted snapshots). So after the log tree is replayed, when
finding orphan roots we hit the BUG_ON with the following trace:

writeback: flush inode cgroup wb switches instead of pinning super_block
If cgroup writeback is in use, inodes can be scheduled for
asynchronous wb switching. Before
5ff8eaac1636 ("writeback: keep
superblock pinned during cgroup writeback association switches"), this
could race with umount leading to super_block being destroyed while
inodes are pinned for wb switching.
5ff8eaac1636 fixed it by bumping
s_active while wb switches are in flight; however, this allowed
in-flight wb switches to make umounts asynchronous when the userland
expected synchronosity - e.g. fsck immediately following umount may
fail because the device is still busy.
This patch removes the problematic super_block pinning and instead
makes generic_shutdown_super() flush in-flight wb switches. wb
switches are now executed on a dedicated isw_wq so that they can be
flushed and isw_nr_in_flight keeps track of the number of in-flight wb
switches so that flushing can be avoided in most cases.
v2: Move cgroup_writeback_umount() further below and add MS_ACTIVE
check in inode_switch_wbs() as Jan an Al suggested.
