Pull LED updates from Jacek Anaszewski:
"New drivers:
- add LED support for MT6323 PMIC
- add LED support for Motorola CPCAP PMIC
New features and improvements:
- add LED trigger for all CPUs aggregated which is useful on tiny
boards with more CPU cores than LED pins
- add OF variants of LED registering functions as a preparation for
adding generic support for Device Tree parsing
- dell-led improvements and cleanups, followed by moving it to the
x86 platform driver subsystem which is a more appropriate place for
it
- extend pca9532 Device Tree support by adding the LEDs
'default-state' property
- extend pca963x Device Tree support by adding nxp,inverted-out
property for inverting the polarity of the output
- remove ACPI support for lp3952 since it relied on a non-official
ACPI IDs"

ASoC: Fixes for v4.11
A few last minute fixes for v4.11, the STI fix is relatively large but
driver specific and has been cooking in -next for a little while now:
- A fix from Takashi for some suspend/resume related crashes in the
Intel drivers.
- A fix from Mousumi Jana for issues with incorrectly created
enumeration controls generated from topology files which could cause
problems for userspace.
- Fixes from Arnaud Pouliquen for some crashes due to races with the
interrupt handler in the STI driver.

The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry
the ignore_suspend flag, and this prevents the suspend/resume working
properly while the stream is running, since SST core code has the
check of the running streams and returns -EBUSY. Drop these
superfluous flags for fixing the behavior.
Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE
definitions, which leads to the kernel Oops at suspend/resume like:

An abstraction of asynchronous transaction for transmission of MIDI
messages was introduced in Linux v4.4. Each driver can utilize this
abstraction to transfer MIDI messages via fixed-length payload of
transaction to a certain unit address. Filling payload of the transaction
is done by callback. In this callback, each driver can return negative
error code, however current implementation assigns the return value to
unsigned variable.
This commit changes type of the variable to fix the bug.

The snd_use_lock_sync() (thus its implementation
snd_use_lock_sync_helper()) has the 5 seconds timeout to break out of
the sync loop. It was introduced from the beginning, just to be
"safer", in terms of avoiding the stupid bugs.
However, as Ben Hutchings suggested, this timeout rather introduces a
potential leak or use-after-free that was apparently fixed by the
commit 2d7d54002e39 ("ALSA: seq: Fix race during FIFO resize"):
for example, snd_seq_fifo_event_in() -> snd_seq_event_dup() ->
copy_from_user() could block for a long time, and snd_use_lock_sync()
goes timeout and still leaves the cell at releasing the pool.
For fixing such a problem, we remove the break by the timeout while
still keeping the warning.

With RTlinux a race condition has been found that leads to NULL ptr crash:
- On CPU 0: uni_player_irq_handler is called to treat XRUN
"(player->state == UNIPERIF_STATE_STOPPED)" is FALSE so status is checked,
dev_err(player->dev, "FIFO underflow error detected") is printed
and then snd_pcm_stream_lock should be called to lock stream for stopping.
- On CPU 1: application stop and close the stream.
Issue is that the stop and shutdown functions are executed while
"FIFO underflow error detected" is printed.
So when CPU 0 calls snd_pcm_stream_lock, player->substream is already null.

At a commit 6c29230e2a5f ("ALSA: oxfw: delayed registration of sound
card"), ALSA oxfw driver fails to handle SCS.1m/1d, due to -EBUSY at a call
of snd_card_register(). The cause is that the driver manages to register
two rawmidi instances with the same device number 0. This is a regression
introduced since kernel 4.7.
This commit fixes the regression, by fixing up device property after
discovering stream formats.

On this Dell AIO machine, the lineout jack does not work.
We found the pin 0x1a is assigned to lineout on this machine, and in
the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the
heaset-set mic problem for this machine, this fixup will redefine
the pin 0x1a to headphone-mic, as a result the lineout doesn't
work anymore.
After consulting with Dell, they told us this machine doesn't support
microphone via headset jack, so we add a new fixup which only defines
the pin 0x18 as the headset-mic.

merge with other branches easier -- tiwai]

ASoC: Fixes for v4.11
A relatively large pile of fixes for mainline, the first since the merge
window. The biggest block of changes here by volume is the sun8i-codec
set, the driver was newly added in the merge window but it was realized
that renaming some of the user visible controls was required so these
are being pushed for v4.11 to avoid the original code appearing in a
release. Otherwise it's all fairly standard bugfix stuff.

When a new event is queued while processing to resize the FIFO in
snd_seq_fifo_clear(), it may lead to a use-after-free, as the old pool
that is being queued gets removed. For avoiding this race, we need to
close the pool to be deleted and sync its usage before actually
deleting it.

When snd_seq_pool_done() is called, it marks the closing flag to
refuse the further cell insertions. But snd_seq_pool_done() itself
doesn't clear the cells but just waits until all cells are cleared by
the caller side. That is, it's racy, and this leads to the endless
stall as syzkaller spotted.
This patch addresses the racy by splitting the setup of pool->closing
flag out of snd_seq_pool_done(), and calling it properly before
snd_seq_pool_done().

CONFIG_SND_X86 is a menu config to filter only for x86-specific
drivers in its sub-menu, and this doesn't have to be tristate but
rather it should be a bool. Also, like other sub-menu configs, it's
more user-friendly to be default=y; it's merely a menu config and the
actual drivers are configured in the sub-menu, after all.

pointer
In 'skl_tplg_set_module_init_data()', a pointer to 'params' member of
'struct skl_algo_data' is calculated, then casted to (u32 *) and assigned
to a member of configuration data. The configuration data is passed to the
other functions and used to process intel IPC. In this processing, the
value of member is used to get message data, however this can bring invalid
memory access in 'skl_set_module_params()' as a result of calculation of
a pointer for actual message data.
