ASoC: samsung: i2s: Simplify pri_dai, sec_dai pointers usage
If the probe call is on the primary DAI we can use 'other' in place of
i2s->sec_dai, if the probe call is on the secondary DAI we can use 'i2s'
in place of other->sec_dai.

While at it fix one whitespace issue.

those of later chips such as Tegra194 which supports a very different

25dc194b34 drm: Block fb changes for async plane updates
The prepare_fb call always happens on new_plane_state.

The drm_atomic_helper_cleanup_planes checks to see if
plane state pointer has changed when deciding to call cleanup_fb on
either the new_plane_state or the old_plane_state.

For a non-async atomic commit the state pointer is swapped, so this
helper calls prepare_fb on the new_plane_state and cleanup_fb on the
old_plane_state. This makes sense, since we want to prepare the
framebuffer we are going to use and cleanup the the framebuffer we are
no longer using.

For the async atomic update helpers this differs. The async atomic
update helpers perform in-place updates on the existing state. They call
drm_atomic_helper_cleanup_planes but the state pointer is not swapped.
This means that prepare_fb is called on the new_plane_state and
cleanup_fb is called on the new_plane_state (not the old).

In the case where old_plane_state->fb == new_plane_state->fb then
there should be no behavioral difference between an async update
and a non-async commit. But there are issues that arise when
old_plane_state->fb != new_plane_state->fb.

The first is that the new_plane_state->fb is immediately cleaned up
after it has been prepared, so we're using a fb that we shouldn't
be.

The second occurs during a sequence of async atomic updates and
non-async regular atomic commits. Suppose there are two framebuffers
being interleaved in a double-buffering scenario, fb1 and fb2:

- Async update, oldfb = NULL, newfb = fb1, prepare fb1, cleanup fb1
- Async update, oldfb = fb1, newfb = fb2, prepare fb2, cleanup fb2
- Non-async commit, oldfb = fb2, newfb = fb1, prepare fb1, cleanup fb2

We call cleanup_fb on fb2 twice in this example scenario, and any
further use will result in use-after-free.

The simple fix to this problem is to block framebuffer changes
in the drm_atomic_helper_async_check function for now.

v2: Move check by itself, add a FIXME (Daniel)

ASoC: samsung: Specify DMA channel names through custom DMA config
This is a part of conversion of Samsung platforms to use the custom DMA
config for specifying DMA channel names, in addition to passing custom
DMA device for the secondary CPU DAI's "PCM" component for some variants
of the I2S controller.

We also don't set the SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME any more
as setting it wouldn't allow to specify DMA channels through the custom
DMA config.

The changes in driver are done in a way so we are backwards compatible
with existing DTS/DTB, i.e. if the cpu sound-dai property contains only

518bfe84ec irqchip/i8259: Fix shutdown order by moving syscore_ops registration
When using cpufreq on Loongson 2F MIPS platform, "poweroff"
command gets frequently stuck in syscore_shutdown(). The reason is
that i8259A_shutdown() gets called before cpufreq_suspend(), and if we
have pending work then irq_work_sync() in cpufreq_dbs_governor_stop()
gets stuck forever as we have all interrupts masked already.

irq-i8259 is registering syscore_ops using device_initcall(),
while cpufreq uses core_initcall(). Fix the shutdown order simply
by registering the irq syscore_ops during the early IRQ init instead
of using a separate initcall at later stage.

540bfab7fb usb: typec: Rationalize the API for the muxes
Since with accessory modes there is no need for additional
identification when requesting a handle to the mux, we can
replace the second parameter that is passed to the
typec_mux_get() function with a pointer to alternate mode
description structure, and simply passing NULL with
accessory modes.

This change means the naming of the mux device connections
can be updated. Alternate and Accessory Modes will both be
handled with muxes named "mode-switch", and the orientation
switches will be named "orientation-switch".

Future identification of the alternate modes will be later
done using device property "svid" of the mux.

1ea61b68d0 async: Add cmdline option to specify drivers to be async probed
Asynchronous driver probing can help much on kernel fastboot, and
this option can provide a flexible way to optimize and quickly verify
async driver probe.

Also it will help in below cases:
* Some driver actually covers several families of HWs, some of which
  could use async probing while others don't. So we can't simply
  turn on the PROBE_PREFER_ASYNCHRONOUS flag in driver, but use this
  cmdline option, like igb driver async patch discussed at
  https://www.spinics.net/lists/netdev/msg545986.html

* For SOC (System on Chip) with multiple spi or i2c controllers, most
  of the slave spi/i2c devices will be assigned with fixed controller
  number, while async probing may make those controllers get different
  index for each boot, which prevents those controller drivers to be
  async probed. For platforms not using these spi/i2c slave devices,
  they can use this cmdline option to benefit from the async probing.

361bf8a9d8 tty/n_hdlc: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/tty/n_hdlc.c: In function ‘n_hdlc_tty_ioctl’:
drivers/tty/n_hdlc.c:775:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   switch (arg) {
   ^~~~~~
drivers/tty/n_hdlc.c:782:2: note: here
  default:
  ^~~~~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

	unsigned int matched = min(startprfx, endprfx);

	struct qstr dname = QSTR_INIT(data + nameoff,

			maxsize - nameoff :
			le16_to_cpu(de[mid + 1].nameoff) - nameoff);

	/* string comparison without already matched prefix */
	int ret = dirnamecmp(name, &dname, &matched);
if le16_to_cpu(de[...].nameoff) is not monotonically increasing?  I.e.
what's to prevent e.g. (unsigned)-1 ending up in dname.len?

Corrupted fs image shouldn't oops the kernel.. "

Revisit the related lookup flow to address the issue.

99944b7306 iwlwifi: mvm: stop static queues correctly
AP interfaces still use some static TX queues (for probes,
broadcast and multicast frames). These queues were not stopped
correctly when the transport layer indicated the queue should be
stopped. As a result, when flushing the queues, new frames from
the overflow queue were tx'd, so the queues still had frames after
flushing. This ended up in an assert since trying to remove a station
with non-empty queues.

Fix it by stopping the static queues correctly when required.

44135b7c53 iwlwifi: mvm: Do not return an error value on HW restart
When HW restart is requested but not started yet, commands would not
be sent to the FW, and some function calls would return an error. In
case of iwl_mvm_mac_sta_state() returning an error value when a
station is removed can lead to an unneeded warning in
__sta_info_destroy_part2().

Handle this by setting the return value to 0, in case HW restart is
in progress.
