927633a6d2 stm class: Fix module init return on allocation failure
In stm_heartbeat_init(): return value gets reset after the first
iteration by stm_source_register_device(), so allocation failures
after that will, after a clean up, return success. Fix that.

3d1cf435e2 driver core: Extend device_is_dependent()
If the device passed as the target (second argument) to
device_is_dependent() is not completely registered (that is, it has
been initialized, but not added yet), but the parent pointer of it
is set, it may be missing from the list of the parent's children
and device_for_each_child() called by device_is_dependent() cannot
be relied on to catch that dependency.

For this reason, modify device_is_dependent() to check the ancestors
of the target device by following its parent pointer in addition to
the device_for_each_child() walk.

 Code: d503201f d50332bf f94002a8 8b344108 (b9000113)

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.

e45122893a x86/fpu: Add kernel_fpu_begin_mask() to selectively initialize state
Currently, requesting kernel FPU access doesn't distinguish which parts of
the extended ("FPU") state are needed.  This is nice for simplicity, but
there are a few cases in which it's suboptimal:

 - The vast majority of in-kernel FPU users want XMM/YMM/ZMM state but do
   not use legacy 387 state.  These users want MXCSR initialized but don't
   care about the FPU control word.  Skipping FNINIT would save time.
   (Empirically, FNINIT is several times slower than LDMXCSR.)

 - Code that wants MMX doesn't want or need MXCSR initialized.
   _mmx_memcpy(), for example, can run before CR4.OSFXSR gets set, and
   initializing MXCSR will fail because LDMXCSR generates an #UD when the
   aforementioned CR4 bit is not set.

 - Any future in-kernel users of XFD (eXtended Feature Disable)-capable
   dynamic states will need special handling.

Add a more specific API that allows callers to specify exactly what they
want.

1c45ba93d3 net: dsa: microchip: Adjust reset release timing to match reference reset circuit
KSZ8794CNX datasheet section 8.0 RESET CIRCUIT describes recommended
circuit for interfacing with CPU/FPGA reset consisting of 10k pullup
resistor and 10uF capacitor to ground. This circuit takes ~100 ms to
rise enough to release the reset.

For maximum supply voltage VDDIO=3.3V VIH=2.0V R=10kR C=10uF that is
                    VDDIO - VIH
  t = R * C * -ln( ------------- ) = 10000*0.00001*-(-0.93)=0.093 s
                       VDDIO
so we need ~95 ms for the reset to really de-assert, and then the
original 100us for the switch itself to come out of reset. Simply
msleep() for 100 ms which fits the constraint with a bit of extra
space.

c369d7fc8f net: dsa: microchip: ksz8795: Fix KSZ8794 port map again
The KSZ8795 switch has 4 external ports {0,1,2,3} and 1 CPU port {4}, so
does the KSZ8765. The KSZ8794 seems to be repackaged KSZ8795 with different
ID and port 3 not routed out, however the port 3 registers are present in
the silicon, so the KSZ8794 switch has 3 external ports {0,1,2} and 1 CPU
port {4}. Currently the driver always uses the last port as CPU port, on
KSZ8795/KSZ8765 that is port 4 and that is OK, but on KSZ8794 that is port
3 and that is not OK, as it must also be port 4.

This patch adjusts the driver such that it always registers a switch with
5 ports total (4 external ports, 1 CPU port), always sets the CPU port to
switch port 4, and then configures the external port mask according to
the switch model -- 3 ports for KSZ8794 and 4 for KSZ8795/KSZ8765.

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.

b135b3358d mtd: rawnand: omap: Use BCH private fields in the specific OOB layout
The OMAP driver may leverage software BCH logic to locate errors while
using its own hardware to detect the presence of errors. This is
achieved with a "mixed" mode which initializes manually the software
BCH internal logic while providing its own OOB layout.

The issue here comes from the fact that the BCH driver has been
updated to only use generic NAND objects, and no longer depend on raw
NAND structures as it is usable from SPI-NAND as well. However, at the
end of the BCH context initialization, the driver checks the validity
of the OOB layout. At this stage, the raw NAND fields have not been
populated yet while being used by the layout helpers, leading to an
invalid layout.

The chosen solution here is to include the BCH structure definition
and to refer to the BCH fields directly (de-referenced as a const
pointer here) to know as early as possible the number of steps and ECC
bytes which have been chosen.

Note: I don't know which commit exactly triggered the error, but the
entire migration to a generic BCH driver got merged in one go, so this
should not be a problem for stable backports.

506c203cc3 ALSA: usb-audio: Fix hw constraints dependencies
Since the recent refactoring, it's been reported that some USB-audio
devices (typically webcams) are no longer detected properly by
PulseAudio.  The debug session revealed that it's failing at probing
by PA to try the sample rate 44.1kHz while the device has discrete
sample rates other than 44.1kHz.  But the puzzle was that arecord
works as is, and some other devices with the discrete rates work,
either.

After all, this turned out to be the lack of the dependencies in a few
hw constraint rules: snd_pcm_hw_rule_add() has the (variable)
arguments specifying the dependent parameters, and some functions
didn't set the target parameter itself as the dependencies.  This
resulted in an invalid parameter that could be generated only in a
certain call pattern.  This bug itself has been present in the code,
but it didn't trigger errors just because the rules were casually
avoiding such a corner case.  After the recent refactoring and
cleanup, however, the hw constraints work "as expected", and the
problem surfaced now.

For fixing the problem above, this patch adds the missing dependent
parameters to each snd_pcm_hw_rule() call.

db58465f11 cachefiles: Drop superfluous readpages aops NULL check
After the recent actions to convert readpages aops to readahead, the
NULL checks of readpages aops in cachefiles_read_or_alloc_page() may
hit falsely.  More badly, it's an ASSERT() call, and this panics.

Drop the superfluous NULL checks for fixing this regression.

[DH: Note that cachefiles never actually used readpages, so this check was
 never actually necessary]

78a18fec52 ACPI: scan: Make acpi_bus_get_device() clear return pointer on error
Set the acpi_device pointer which acpi_bus_get_device() returns-by-
reference to NULL on errors.

We've recently had 2 cases where callers of acpi_bus_get_device()
did not properly error check the return value, so set the returned-
by-reference acpi_device pointer to NULL, because at least some
callers of acpi_bus_get_device() expect that to be done on errors.

[ rjw: This issue was exposed by commit 71da201f38 ("ACPI: scan:
  Defer enumeration of devices with _DEP lists") which caused it to
  be much more likely to occur on some systems, but the real defect
  had been introduced by an earlier commit. ]
