I can reliably reproduce this problem by running 'tail' on the registers
file in debugfs for the hdmi regmap.

 # tail /sys/kernel/debug/regmap/62d87000.lpass-lpass_hdmi/registers
 [   84.658733] Unable to handle kernel paging request at virtual address ffffffd0128e800c

This crash happens because we're trying to read registers from the
regmap beyond the length of the mapping created by ioremap().

The number of hdmi_rdma_channels determines the size of the regmap via
this code in sound/soc/qcom/lpass-cpu.c:

  lpass_hdmi_regmap_config.max_register = LPAIF_HDMI_RDMAPER_REG(variant, variant->hdmi_rdma_channels);

According to debugfs the size of the regmap is 0x68010 but according to
the DTS file posted in [1] the size is only 0x68000 (see the first reg
property of the lpass_cpu node). Let's change the number of channels to
be 3 instead of 4 so the math works out to have a max register of
0x67010, nicely fitting inside of the region size of 0x68000.

Note: I tried to bump up the size of the register region to the next
page to include the 0x68010 register but then the tail command caused
SErrors with an async abort, implying that the register region doesn't
exist or it isn't clocked because the bus is telling us that the
register read failed. I reduce the number of channels and played audio
through the HDMI channel and it kept working so I think this is correct.

Merge series "ASoC: qcom: Fix broken lpass driver" from Srinivas Kandagatla <srinivas.kandagatla@linaro.org>:

LPASS driver is partially broken on DragonBoard DB410c on 5.10 and
its totally broken on other Supported Qualcomm SoCs.

This was due to DAI ids being over written by the SoC specific header files
in the dt-bindings.

Idea of having SoC specific headers is not doable when we are dealing with
a common driver. So this patchset attempts to fix this properly by creating
a common dt-bindings header for lpass which can be updated with new entries
if required. This patchset also add an simple of_xlate function to resolve
the dai names and different SoCs might not have 1:1 mapping for the
dai_driver array with dai ids.

Changes since v1:
	- removed array indexes as suggested by Stephan G.
	- rebased to sound/for-next branch
	- collected Srinivasa tested-by tag for sc7180 platform.

Thanks,
srini

Merge series "Add KUNIT tests for ASoC topology" from Amadeusz Sławiński<amadeuszx.slawinski@linux.intel.com>:

This series adds unit tests for ASoC topology.

First fix problems found when developing and running test cases and
then add tests implementation.

Tests themselves are quite simple and just call
snd_soc_tplg_component_load() with various parameters and check the
result. Tests themselves are described in more detail in commits
adding them.

Goal is to expand the amount of test cases in following patches.

Prerequisity for this patchset are 2 patches which have already been
sent:
https://lore.kernel.org/alsa-devel/20210114163602.911205-1-amadeuszx.slawinski@linux.intel.com/T/#t

Description on how typical test case itself works:

In order to load topology we need to have 3 things:
card, codec component & platform component.

In typical test case we register card and platform component and bind
to dummy codec. There are of course execeptions, when we want to
test behaviour of topology API when component or card is missing.
Note that this is bit different from typical scenario (in SOF and skylake
drivers) where card is registered by machine driver and component by
platform driver, as we register both when setting up test.

If you check the test case most of them have similar architecture of:
1.
	/* run test */
	ret = snd_soc_register_card(&kunit_comp->card);
	if (ret != 0 && ret != -EPROBE_DEFER)
		KUNIT_FAIL(test, "Failed to register card");

2.
	ret = snd_soc_component_initialize(&kunit_comp->comp, &test_component, test_dev);
	KUNIT_EXPECT_EQ(test, 0, ret);

3.
	ret = snd_soc_add_component(&kunit_comp->comp, NULL, 0);
	KUNIT_EXPECT_EQ(test, 0, ret);

Ad. 1.
First we register card, which in most tests returns -EPROBE_DEFER
(from snd_soc_bind_card()), as platform component is not yet created.
I test for both 0 and -EPROBE_DEFER, as it makes it easier to reshuffle
this code around if needed and there is one test case which does it in
different order.

Ad. 2.
Then we initialize platform component with structure pointing at proper
probe function, which calls snd_soc_tplg_component_load() with test
parameters and checks expected result.

Ad. 3.
And then in follow up we call snd_soc_add_component() which creates
platform component for us and calls snd_soc_try_rebind_card() which
if everything is bound properly calls previously set probe function.

lpass hdmi support patch totally removed support for MI2S TERTIARY
and QUATERNARY.

One of the major issue was spotted with the design of having
separate SoC specific header files for the common lpass driver.
This design is prone to break as an when new SoC header is added
as the common DAI ids of other SoCs will be overwritten by the
new ones.

Having a common header qcom,lpass.h should fix the issue and any new
DAI ids should be added to the common header.

With this change lpass also needs a new of_xlate function to resolve
dai name.

The earlier commit to fix runtime PM in case i915 init fails,
introduces a possibility to hit a page fault.

snd_hdac_ext_bus_device_exit() is designed to be called from
dev.release(). Calling it outside device reference counting, is
not safe and may lead to calling the device_exit() function
twice. Additionally, as part of ext_bus_device_init(), the device
is also registered with snd_hdac_device_register(). Thus before
calling device_exit(), the device must be removed from device
hierarchy first.

Fix the issue by rolling back init actions by calling
hdac_device_unregister() and then releasing device with put_device().
This matches with existing code in hdac-ext module.

To complete the fix, add handling for the case where
hda_codec_load_module() returns -ENODEV, and clean up the hdac_ext
resources also in this case.

In future work, hdac-ext interface should be extended to allow clients
more flexibility to handle the life-cycle of individual devices, beyond
just the current snd_hdac_ext_bus_device_remove(), which removes all
devices.

That commit keeps the codec suspended during the system suspend. However,
mute/micmute LED will clear codec's direct-complete flag by
dpm_clear_superiors_direct_complete().

This doesn't play well with SOF driver. When its runtime resume is
called for system suspend, hda_codec_jack_check() schedules
jackpoll_work which uses snd_hdac_is_power_on() to check whether codec
is suspended. Because the direct-complete path isn't taken,
pm_runtime_disable() isn't called so snd_hdac_is_power_on() returns
false and jackpoll continues to run, and snd_hda_power_up_pm() cannot
power up an already suspended codec in multiple attempts, causes the
long delay on system suspend:

if (dev->power.direct_complete) {
	if (pm_runtime_status_suspended(dev)) {
		pm_runtime_disable(dev);
		if (pm_runtime_status_suspended(dev)) {
			pm_dev_dbg(dev, state, "direct-complete ");
			goto Complete;
		}

		pm_runtime_enable(dev);
	}
	dev->power.direct_complete = false;
}

When direct-complete path is taken, snd_hdac_is_power_on() returns true
and hda_jackpoll_work() is skipped by accident. So this is still not
correct.

If we were to use snd_hdac_is_power_on() in system PM path,
pm_runtime_status_suspended() should be used instead of
pm_runtime_suspended(), otherwise pm_runtime_{enable,disable}() may
change the outcome of snd_hdac_is_power_on().

Because devices suspend in reverse order (i.e. child first), it doesn't
make much sense to resume an already suspended codec from audio
controller. So avoid the issue by making sure jackpoll isn't used in
system PM process.

Pull SCSI fixes from James Bottomley:
 "This is two driver fixes (megaraid_sas and hisi_sas).

  The megaraid one is a revert of a previous revert of a cpu hotplug fix
  which exposed a bug in the block layer which has been fixed in this
  merge window.

  The hisi_sas performance enhancement comes from switching to interrupt
  managed completion queues, which depended on the addition of
  devm_platform_get_irqs_affinity() which is now upstream via the irq
  tree in the last merge window"

When the creator of SQPOLL io_uring dies (i.e. sqo_task), we don't want
its internals like ->files and ->mm to be poked by the SQPOLL task, it
have never been nice and recently got racy. That can happen when the
owner undergoes destruction and SQPOLL tasks tries to submit new
requests in parallel, and so calls io_sq_thread_acquire*().

That patch halts SQPOLL submissions when sqo_task dies by introducing
sqo_dead flag. Once set, the SQPOLL task must not do any submission,
which is synchronised by uring_lock as well as the new flag.

The tricky part is to make sure that disabling always happens, that
means either the ring is discovered by creator's do_exit() -> cancel,
or if the final close() happens before it's done by the creator. The
last is guaranteed by the fact that for SQPOLL the creator task and only
it holds exactly one file note, so either it pins up to do_exit() or
removed by the creator on the final put in flush. (see comments in
uring_flush() around file->f_count == 2).

One more place that can trigger io_sq_thread_acquire_*() is
__io_req_task_submit(). Shoot off requests on sqo_dead there, even
though actually we don't need to. That's because cancellation of
sqo_task should wait for the request before going any further.

note 1: io_disable_sqo_submit() does io_ring_set_wakeup_flag() so the
caller would enter the ring to get an error, but it still doesn't
guarantee that the flag won't be cleared.

note 2: if final __userspace__ close happens not from the creator
task, the file note will pin the ring until the task dies.
