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

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".

a user would adjust when testing non-thresholding cases.
However, MCA_MISC is unconditionally written even if a user does not
supply a value. The default value of '0' will be used and clobber the
register.

struct platform_driver::remove returning an integer made driver authors
expect that returning an error code was proper error handling. However
the driver core ignores the error and continues to remove the device
because there is nothing the core could do anyhow and reentering the
remove callback again is only calling for trouble.
To prevent such wrong assumptions, change the return type of the remove
callback to void. This was prepared by introducing an alternative remove
callback returning void and converting all drivers to that. So .remove()
can be changed without further changes in drivers.
This corresponds to step b) of the plan outlined in commit
5c5a7680e6 ("platform: Provide a remove callback that returns no value").

Commit b8b8b4e0c0 ("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 7edbb60592 ("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 b8b8b4e0c0 ("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.

The 2024 ASUS ROG G814J model is much the same as the 2023 model
and the 2023 16" version. We can use the same Cirrus Amp quirk.

The card-specific debugfs entries are removed at the last stage of
card free phase, and it's performed after synchronization of the
closes of all opened fds. This works fine for most cases, but it can
be potentially problematic for a hotplug device like USB-audio. Due
to the nature of snd_card_free_when_closed(), the card free isn't
called immediately after the driver removal for a hotplug device, but
it's left until the last fd is closed. It implies that the card
debugfs entries also remain. Meanwhile, when a new device is inserted
before the last close and the very same card slot is assigned, the
driver tries to create the card debugfs root again on the very same
path. This conflicts with the remaining entry, and results in the
kernel warning such as:
debugfs: Directory 'card0' with parent 'sound' already present!
with the missing debugfs entry afterwards.
For avoiding such conflicts, remove debugfs entries at the device
disconnection phase instead. The jack kctl debugfs entries get
removed in snd_jack_dev_disconnect() instead of each kctl
private_free.
