c45f726310 firmware: stratix10-rsu: Fix NULL pointer dereference when RSU is disabled
When the Remote System Update (RSU) isn't enabled in the First Stage
Boot Loader (FSBL), the driver encounters a NULL pointer dereference when
excute svc_normal_to_secure_thread() thread, resulting in a kernel panic:

Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008

---[ end trace 0000000000000000 ]---

The issue occurs because rsu_send_async_msg() fails when RSU is not enabled
in firmware, causing the channel to be freed via stratix10_svc_free_channel().
However, the probe function continues execution and registers
svc_normal_to_secure_thread(), which subsequently attempts to access the
already-freed channel, triggering the NULL pointer dereference.

Fix this by properly cleaning up the async client and returning early on
failure, preventing the thread from being used with an invalid channel.

9990cd4f88 iio: imu: adis: Fix NULL pointer dereference in adis_init
The adis_init() function dereferences adis->ops to check if the
individual function pointers (write, read, reset) are NULL, but does
not first check if adis->ops itself is NULL.

Drivers like adis16480, adis16490, adis16545 and others do not set
custom ops and rely on adis_init() assigning the defaults. Since struct
adis is zero-initialized by devm_iio_device_alloc(), adis->ops is NULL
when adis_init() is called, causing a NULL pointer dereference:

    Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
    pc : adis_init+0xc0/0x118
    Call trace:
     adis_init+0xc0/0x118
     adis16480_probe+0xe0/0x670

Fix this by checking if adis->ops is NULL before dereferencing it,
falling through to assign the default ops in that case.

2617595538 iio: imu: inv_icm45600: fix regulator put warning when probe fails
When the driver probe fails we encounter a regulator put warning
because vddio regulator is not stopped before release. The issue
comes from pm_runtime not already setup when core probe fails and
the vddio regulator disable callback is called.

Fix the issue by setting pm_runtime active early before vddio
regulator resource cleanup. This requires to cut pm_runtime
set_active and enable in 2 function calls.

acc3949aab iio: gyro: mpu3050-core: fix pm_runtime error handling
The return value of pm_runtime_get_sync() is not checked, allowing
the driver to access hardware that may fail to resume. The device
usage count is also unconditionally incremented. Use
pm_runtime_resume_and_get() which propagates errors and avoids
incrementing the usage count on failure.

In preenable, add pm_runtime_put_autosuspend() on set_8khz_samplerate()
failure since postdisable does not run when preenable fails.

This function refers to the Bosch BME680 API as the source of the

EBUSY to user space.

errors.

85e4614524 iio: potentiometer: mcp4131: fix double application of wiper shift
The MCP4131 wiper address is shifted twice when preparing the SPI
command in mcp4131_write_raw().

The address is already shifted when assigned to the local variable
"address", but is then shifted again when written to data->buf[0].
This results in an incorrect command being sent to the device and
breaks wiper writes to the second channel.

Remove the second shift and use the pre-shifted address directly
when composing the SPI transfer.

The blamed commit was tested with mpu6050 in lg,p895 and lg,p880 according
to Tested-bys. But with the MPU9150 in the Epson Moverio BT-200 this leads

6c8bf4b604 iio: frequency: adf4377: Fix duplicated soft reset mask
The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK
twice instead of checking both SOFT_RESET_MSK (bit 0) and
SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check.

The code first sets both SOFT_RESET and SOFT_RESET_R bits to 1 via
regmap_update_bits(), then polls for them to be cleared. Since we set
both bits before polling, we should be waiting for both to clear.

Fix by using both masks as done in regmap_update_bits() above.

ODR switch is done in 2 steps when FIFO is on : change the ODR register
value and acknowledge change when reading the FIFO ODR change flag.
When we are switching odr and turning buffer off just afterward, we are
losing the FIFO ODR change flag and ODR switch is blocked.

Fix the issue by force applying any waiting ODR change when turning

32a92f8c89 Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

323bbfcf1e Convert 'alloc_flex' family to use the new default GFP_KERNEL argument
This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.

As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

e19e1b480a add default_gfp() helper macro and use it in the new *alloc_obj() helpers
Most simple allocations use GFP_KERNEL, and with the new allocation
helpers being introduced, let's just take advantage of that to simplify
that default case.

It's a numbers game:

    git grep 'alloc_obj(' |
	sed 's/.*\(GFP_[_A-Z]*\).*/\1/' |
	sort | uniq -c | sort -n | tail

shows that about 90% of all those new allocator instances just use that
standard GFP_KERNEL.

Those helpers are already macros, and we can easily just make it be the
default case when the gfp argument is missing.

And yes, we could do that for all the legacy interfaces too, but let's
keep it to just the new ones at least for now, since those all got
converted recently anyway, so this is not any "extra" noise outside of
that limited conversion.

And, in fact, I want to do this before doing the -rc1 release, exactly
so that we don't get extra merge conflicts.

fa5c82f4d2 slab.h: disable completely broken overflow handling in flex allocations
Commit 69050f8d6d ("treewide: Replace kmalloc with kmalloc_obj for
non-scalar types") started using the new allocation helpers, and in the
process showed that they were completely non-working.

The overflow logic in overflows_flex_counter_type() is completely the
wrong way around, and that broke __alloc_flex() completely.  By chance,
the resulting code was then such a mess that clang generated
sufficiently garbage code that objtool warned about it all.  Which made
it somewhat quicker to narrow things down.

While fixing overflows_flex_counter_type() would presumably fix this
all, I'm excising the whole broken overflow logic from __alloc_flex(),
because we don't want that kind of code in basic allocation functions
anyway.

That (no longer) broken overflows_flex_counter_type() thing needs to be
inserted into the actual __set_flex_counter() logic in the unlikely case
that we ever want this at all.  And made conditional.

   to select fields using 'perf report''s -F/-fields, e.g.:
 
     'perf report --fields overhead,type'
 
 - Add 'perf test' regression tests for Data-type profiling with
   C and Rust workloads.
 
 - Fix srcline printing with inlines in callchains, make sure this has
   coverage in 'perf test'.

bb1c9ccf74 scripts: coccicheck: warn on unset debug file
coccicheck prints debug logs to stdout unless a debug file has been set.
This makes it hard to read coccinelle's suggested changes, especially
for someone new to coccicheck.

From this commit, we warn about this behaviour from within the script on
an unset debug file. Explicitly setting the debug file to /dev/null
suppresses the warning while keeping the default.
