705e9994a4 ASoC: rockchip: constify snd_soc_ops structures
Check for snd_soc_ops structures that are only stored in the ops field of a
snd_soc_dai_link structure.  This field is declared const, so snd_soc_ops
structures that have this property can be declared as const also.

The semantic patch that makes this change is as follows:

e0af98a7e0 spi: mark device nodes only in case of successful instantiation
Instantiated SPI device nodes are marked with OF_POPULATE. This was
introduced in bd6c164. On unloading, loaded device nodes will of course
be unmarked. The problem are nodes that fail during initialisation: If a
node fails, it won't be unloaded and hence not be unmarked.

If a SPI driver module is unloaded and reloaded, it will skip nodes that
failed before.

Skip device nodes that are already populated and mark them only in case
of success.

Note that the same issue exists for I2C.

028f5a5bc8 ASoC: wm8580: Add the wm8581 codec to the driver
This patch adds support for the wm8581 codec to the wm8580 driver.
The wm8581 codec hardware adds a fourth DAC and otherwise is
compatible with the wm8580 codec.

of_device_id data is used to allow the driver to select the
suitable DAC count specified in the device tree codec selection.
The wm8580_driver_data struct is used to store the number of DACs.

The snd_soc_dai_driver no longer lists the channels_max for the
playback substream. This variable is set during the i2c probe
from the of_device_id supplied wm8580_driver_data struct.

With knowledge of the number of DACs in use, the DAC4 controls,
widgets and routes are added as required for DAC4.

The device tree documentation for the wm8580 is altered to list
the wm8581 codec support, as is the Kconfig file.

cf986d4702 ARCv2: IOC: use @ioc_enable not @ioc_exist where intended
if user disables IOC from debugger at startup (by clearing @ioc_enable),
@ioc_exists is cleared too. This means boot prints don't capture the
fact that IOC was present but disabled which could be misleading.

So invert how we use @ioc_enable and @ioc_exists and make it more
canonical. @ioc_exists represent whether hardware is present or not and
stays same whether enabled or not. @ioc_enable is still user driven,
but will be auto-disabled if IOC hardware is not present, i.e. if
@ioc_exist=0. This is opposite to what we were doing before, but much
clearer.

This means @ioc_enable is now the "exported" toggle in rest of code such
as dma mapping API.

which need atomic primitives. So enable them by providing kernel assist.
This is costly but really the only sane soluton (othern than tight
spinning using the otherwise availiable atomic exchange EX instruciton).

Good thing is there are only a few of these cores running Linux out in
the wild.

This only works on UP systems.

9c894696f5 Btrfs: remove some no-op casts
We cast 0 to a u8 but then because of type promotion, it's immediately
cast to int back to int before we do a bitwise negate.  The cast doesn't
matter in this case, the code works as intended.  It causes a static
checker warning though so let's remove it.

dd4b857aab btrfs: pass correct args to btrfs_async_run_delayed_refs()
In btrfs_truncate_inode_items()->btrfs_async_run_delayed_refs(), we
swap the arg2 and arg3 wrongly, fix this.

This bug just impacts asynchronous delayed refs handle when we truncate inodes.
In delayed_ref_async_start(), there is such codes:

    trans = btrfs_join_transaction(async->root);
    if (trans->transid > async->transid)
        goto end;
    ret = btrfs_run_delayed_refs(trans, async->root, async->count);

From this codes, we can see that this just influence whether can we handle
delayed refs or the number of delayed refs to handle, this may impact
performance, but will not result in missing delayed refs, all delayed refs will
be handled in btrfs_commit_transaction().

0b34c261e2 btrfs: qgroup: Prevent qgroup->reserved from going subzero
While free'ing qgroup->reserved resources, we much check if
the page has not been invalidated by a truncate operation
by checking if the page is still dirty before reducing the
qgroup resources. Resources in such a case are free'd when
the entire extent is released by delayed_ref.

This fixes a double accounting while releasing resources
in case of truncating a file, reproduced by the following testcase.

SCRATCH_DEV=/dev/vdb
SCRATCH_MNT=/mnt
mkfs.btrfs -f $SCRATCH_DEV
mount -t btrfs $SCRATCH_DEV $SCRATCH_MNT
cd $SCRATCH_MNT
btrfs quota enable $SCRATCH_MNT
btrfs subvolume create a
btrfs qgroup limit 500m a $SCRATCH_MNT
sync
for c in {1..15}; do
dd if=/dev/zero  bs=1M count=40 of=$SCRATCH_MNT/a/file;
done

sleep 10
sync
sleep 5

touch $SCRATCH_MNT/a/newfile

echo "Removing file"
rm $SCRATCH_MNT/a/file

86a6c211d6 NFS: Trim extra slash in v4 nfs_path
A NFSv4 mount of a subdirectory will show an extra slash (as in
'server://path') in proc's mountinfo which will not match the device name
and path.  This can cause problems for programs searching for the mount.
Fix this by checking for a leading slash in the dentry path, if so trim
away any trailing slashes in the device name.

With the new reinitialization method, configuring parity, different
frame lengths and different stop bit settings should work as expected
on both CH340G and CH341A. Tested on a loopback-connected CH340G
with a logic analyzer in a number of different configurations.

4e46c410e0 USB: serial: ch341: reinitialize chip on reconfiguration
Changing the LCR register after initialization does not seem to be reliable
on all chips (particularly not on CH341A). Restructure initialization and
configuration to always reinit the chip on configuration changes instead and
pass the LCR register value directly to the initialization command.

(Note that baud rates above 500kbaud are incorrect, but they're incorrect in
the same way both before and after this patch at least on the CH340G. Fixing
this isn't a priority as higher baud rates don't seem that reliable anyway.)

dafa724bf5 dm table: fix missing dm_put_target_type() in dm_table_add_target()
dm_get_target_type() was previously called so any error returned from
dm_table_add_target() must first call dm_put_target_type().  Otherwise
the DM target module's reference count will leak and the associated
kernel module will be unable to be removed.

Also, leverage the fact that r is already -EINVAL and remove an extra
newline.

Some devices have invalid baSourceID references, causing uvc_scan_chain()
to fail, but if we just take the entities we can find and put them
together in the most sensible chain we can think of, turns out they do
work anyway. Note: This heuristic assumes there is a single chain.

At the time of writing, devices known to have such a broken chain are
  - Acer Integrated Camera (5986:055a)
