When devm_regmap_init_i2c() fails, regmap_ee could be error pointer,
instead of checking for IS_ERR(regmap_ee), regmap is checked which looks
like a copy paste error.

In case of error in the bmi323_trigger_handler() function, the
function exits without calling the iio_trigger_notify_done()
which is responsible for informing the attached trigger that
the process is done and in case there is a .reenable(), to
call it.

The scale value for the temperature channel is (assuming Vref=2.5 and
the datasheet):
376.7897513
When calculating both val and val2 for the temperature scale we
use (3767897513/25) and multiply it by Vref (here I assume 2500mV) to
obtain:
2500 * (3767897513/25) ==> 376789751300
Finally we divide with remainder by 10^9 to get:
val = 376
val2 = 789751300
However, we return IIO_VAL_INT_PLUS_MICRO (should have been NANO) as
the scale type. So when converting the raw temperature value to the
'processed' temperature value we will get (assuming raw=810,
offset=-753):
processed = (raw + offset) * scale_val
= (810 + -753) * 376
= 21432
processed += div((raw + offset) * scale_val2, 10^6)
+= div((810 + -753) * 789751300, 10^6)
+= 45015
==> 66447
==> 66.4 Celcius
instead of the expected 21.5 Celsius.
Fix this issue by changing IIO_VAL_INT_PLUS_MICRO to
IIO_VAL_INT_PLUS_NANO.

For BMP18x, BMP28x, BME280, BMP38x the reading of the pressure
value requires an update of the t_fine variable which happens
through reading the temperature value.
So all the bmpxxx_read_press() functions of the above sensors
are internally calling the equivalent bmpxxx_read_temp() function
in order to update the t_fine value. By just looking at the code
this functionality is a bit hidden and is not easy to understand
why those channels are not independent.
This commit tries to clear these things a bit by splitting the
bmpxxx_{read/compensate}_{temp/press/humid}() to the following:
i. bmpxxx_read_{temp/press/humid}_adc(): read the raw value from
the sensor.
ii. bmpxx_calc_t_fine(): calculate the t_fine variable.
iii. bmpxxx_get_t_fine(): get the t_fine variable.
iv. bmpxxx_compensate_{temp/press/humid}(): compensate the adc
values and return the calculated value.
v. bmpxxx_read_{temp/press/humid}(): combine calls of the
aforementioned functions to return the requested value.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

The bmp180_measure() function essentially waits for the end of the
current conversion in order to read the values from the sensors. The
name bmp180_measure() could be misinterpreted because it could be
translated as "measure sensor values" even though it was probably
trying to say "measure time for eoc". Give a more intuitive name
to this function to be less confusing.

The iio_gts helpers build available times and scales tables based on the
times and gains arrays given from the driver. The driver should be able
to list all valid register values so that conversion from register valu
to correct gain/time works for all supported register values.
It might be more convenient for drivers to list these times and gains in
the order where they're listed in the data-sheet than ascending order.
However, for user who requests the supported scales / times it is more
convenient to get the results in asscending order. Also, listing
duplicated values is not meaning for the user.
Hence the GTS heler should do sorting and deduplication of the scales
and times when it builds the tables listing the available times/scales.
Note, currently duplicated gain values aren't handled by GTS-helpers.
Unsort the gain and time arrays in the test code, and add duplicates to
time array in order to test the sorting and deduplicating works.

The sorting in iio_gts_build_avail_time_table is not working as intended.
It could result in an out-of-bounds access when the time is zero.
Here are more details:
1. When the gts->itime_table[i].time_us is zero, e.g., the time
sequence is `3, 0, 1`, the inner for-loop will not terminate and do
out-of-bound writes. This is because once `times[j] > new`, the value
`new` will be added in the current position and the `times[j]` will be
moved to `j+1` position, which makes the if-condition always hold.
Meanwhile, idx will be added one, making the loop keep running without
termination and out-of-bound write.
2. If none of the gts->itime_table[i].time_us is zero, the elements
will just be copied without being sorted as described in the comment
"Sort times from all tables to one and remove duplicates".
For more details, please refer to

Commit b8b8b4e0c052 ("ata: ahci: Add Intel Alder Lake-P AHCI controller
to low power chipsets list") added Intel Alder Lake to the ahci_pci_tbl.
Because of the way that the Intel PCS quirk was implemented, having
an explicit entry in the ahci_pci_tbl caused the Intel PCS quirk to
be applied. (The quirk was not being applied if there was no explict
entry.)
Thus, entries that were added to the ahci_pci_tbl also got the Intel
PCS quirk applied.
The quirk was cleaned up in commit 7edbb6059274 ("ahci: clean up
intel_pcs_quirk"), such that it is clear which entries that actually
applies the Intel PCS quirk.
Newer Intel AHCI controllers do not need the Intel PCS quirk,
and applying it when not needed actually breaks some platforms.
Do not apply the Intel PCS quirk for Intel Alder Lake.
This is in line with how things worked before commit b8b8b4e0c052 ("ata:
ahci: Add Intel Alder Lake-P AHCI controller to low power chipsets list"),
such that certain platforms using Intel Alder Lake will work once again.

Currently, when an adapter defines a max_write_len quirk,
the data will be chunked into data sizes equal to the
max_write_len quirk value. But the payload will be increased by
the size of the register address before transmission. The
resulting value always ends up larger than the limit set
by the quirk.
Avoid this error by setting regmap's max_write to the quirk's
max_write_len minus the number of bytes for the register and
padding. This allows the chunking to work correctly for this
limited case without impacting other use-cases.

A potential deadlock was reported with the config file at
https://web.archive.org/web/20240522052129/https://0x0.st/XPN_.txt
In this particular configuration, the deadlock doesn't exist because
the warning triggered at a point before modules were even available.
However, the deadlock can be real because any module loaded would
invoke async_synchronize_full.
The issue is spurious for software crypto algorithms which aren't
themselves involved in async probing. However, it would be hard to
avoid for a PCI crypto driver using async probing.
In this particular call trace, the problem is easily avoided because
the only reason the module is being requested during probing is the
add_early_randomness call in the hwrng core. This feature is
vestigial since there is now a kernel thread dedicated to doing
exactly this.
So remove add_early_randomness as it is no longer needed.

When running Cilium connectivity test suite with netkit in L2 mode, we
found that compared to tcx a few tests were failing which pushed traffic
into an L7 proxy sitting in host namespace. The problem in particular is
around the invocation of eth_type_trans() in netkit.
In case of tcx, this is run before the tcx ingress is triggered inside
host namespace and thus if the BPF program uses the bpf_skb_change_type()
helper the newly set type is retained. However, in case of netkit, the
late eth_type_trans() invocation overrides the earlier decision from the
BPF program which eventually leads to the test failure.
Instead of eth_type_trans(), split out the relevant parts, meaning, reset
of mac header and call to eth_skb_pkt_type() before the BPF program is run
in order to have the same behavior as with tcx, and refactor a small helper
called eth_skb_pull_mac() which is run in case it's passed up the stack
where the mac header must be pulled. With this all connectivity tests pass.

bio_vec start offset may be relatively large particularly when large
folio gets added to the bio. A bigger offset will result in avoiding the
single-segment mapping optimization and end up using expensive
mempool_alloc further.
Rather than using absolute value, adjust bv_offset by
NVME_CTRL_PAGE_SIZE while checking if segment can be fitted into one/two
PRP entries.

Since commit a6aa8fca4d79 ("dma-buf/sw-sync: Reduce irqsave/irqrestore from
known context") by error replaced spin_unlock_irqrestore() with
spin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despite
sync_print_obj() is called from sync_debugfs_show(), lockdep complains
inconsistent lock state warning.
Use plain spin_{lock,unlock}() for sync_print_obj(), for
sync_debugfs_show() is already using spin_{lock,unlock}_irq().

Previously, the driver incorrectly used rx_dropped to report device
buffer exhaustion.
According to the documentation, rx_dropped should not be used to count
packets dropped due to buffer exhaustion, which is the purpose of
rx_missed_errors.
Use rx_missed_errors as intended for counting packets dropped due to
buffer exhaustion.

The ptp channel instance is only initialized when ptp traffic is first
processed by the driver. This means that there is a window in between when
port timestamping is enabled and ptp traffic is sent where the ptp channel
instance is not initialized. Accessing statistics during this window will
lead to an access violation (NULL + member offset). Check the validity of
the instance before attempting to query statistics.

Currently, the driver does not enforce that lag bond slaves must have
matching roce capabilities. Yet, in mlx5_do_bond(), the driver attempts
to enable roce on all vports of the bond slaves, causing the following
syndrome when one slave has no roce fw support:
mlx5_cmd_out_err:809:(pid 25427): MODIFY_NIC_VPORT_CONTEXT(0×755) op_mod(0×0)
failed, status bad parameter(0×3), syndrome (0xc1f678), err(-22)
Thus, create HW lag only if bond's slaves agree on roce state,
either all slaves have roce support resulting in a roce lag bond,
or none do, resulting in a raw eth bond.
