This fix is already present in f_ecm.c and was never
propagated to f_ncm.c
When creating multiple NCM ethernet devices
on a composite usb gadget device
each MAC address on the HOST side will be identical.
Having the same MAC on different network interfaces is bad.
This fix updates the MAC address inside the
ncm_strings_defs global during the ncm_bind call.
This ensures each device has a unique MAC.
In f_ecm.c ecm_string_defs is updated in the same way.
The defunct MAC assignment in ncm_alloc has been removed.

UCSI specification v2.1 and above to debugfs.
Following power related fields will be exposed as files in debugfs:-
peak_current (Peak current),
avg_current (Average current) and
vbus_voltage (VBUS voltage)
These files will be updated either when a READ_POWER_LEVEL

Presently in `max_contaminant_is_contaminant()` if there's no
contaminant detected previously, CC is open & stopped toggling and no
contaminant is currently present, TCPC.RC would be programmed to do DRP
toggling. However, it didn't actively look for a connection. This would
lead to Type-C not detect *any* new connections. Hence, in the above
situation, re-enable toggling & program TCPC to look for a new
connection.
Also, return early if TCPC was looking for connection as this indicates
TCPC has neither detected a potential connection nor a change in
contaminant state.
In addition, once dry detection is complete (port is dry), restart
toggling.

Low power mode is enabled when reading CC resistance as part of
`max_contaminant_read_resistance_kohm()` and left in that state.
However, it's supposed to work with 1uA current source. To read CC
comparator values current source is changed to 80uA. This causes a storm
of CC interrupts as it (falsely) detects a potential contaminant. To
prevent this, disable low power mode current sourcing before reading
comparator values.

This commit addresses a rarely observed endpoint command timeout
which causes kernel panic due to warn when 'panic_on_warn' is enabled
and unnecessary call trace prints when 'panic_on_warn' is disabled.
It is seen during fast software-controlled connect/disconnect testcases.
The following is one such endpoint command timeout that we observed:
1. Connect
=======
->dwc3_thread_interrupt
->dwc3_ep0_interrupt
->configfs_composite_setup
->composite_setup
->usb_ep_queue
->dwc3_gadget_ep0_queue
->__dwc3_gadget_ep0_queue
->__dwc3_ep0_do_control_data
->dwc3_send_gadget_ep_cmd
2. Disconnect
==========
->dwc3_thread_interrupt
->dwc3_gadget_disconnect_interrupt
->dwc3_ep0_reset_state
->dwc3_ep0_end_control_data
->dwc3_send_gadget_ep_cmd
In the issue scenario, in Exynos platforms, we observed that control
transfers for the previous connect have not yet been completed and end
transfer command sent as a part of the disconnect sequence and
processing of USB_ENDPOINT_HALT feature request from the host timeout.
This maybe an expected scenario since the controller is processing EP
commands sent as a part of the previous connect. It maybe better to
remove WARN_ON in all places where device endpoint commands are sent to
avoid unnecessary kernel panic due to warn.

Many Realtek USB Wi-Fi dongles released in recent years have two modes:
one is driver CD mode which has Windows driver onboard, another one is
Wi-Fi mode. Add the US_FL_IGNORE_DEVICE quirk for these multi-mode devices.
Otherwise, usb_modeswitch may fail to switch them to Wi-Fi mode.
Currently there are only two USB IDs known to be used by these multi-mode
Wi-Fi dongles: 0bda:1a2b and 0bda:a192.

The minimum supported version of GCC to build the x86 kernel was bumped

a3e8fe814a ("x86/build: Raise the minimum GCC version to 8.1").
Prior to GCC 7.1, '-mpreferred-stack-boundary=3' was not allowed with
'-msse', so areas of the kernel that needed floating point had a
different alignment. Now that GCC > 7.1 is mandatory, there is no need
to have a different value of '-mpreferred-stack-boundary' from the rest
of the kernel, so remove this handling from CC_FLAGS_FPU.

In param_set_copystring(), we can safely use memcpy() because we already

When stress-testing the system by repeatedly unbinding and binding the ADC
device in a loop, and the ADC is a supplier for another device (e.g., a
thermal hardware block that reads temperature through the ADC), it may
happen that the ADC device is runtime-resumed immediately after runtime PM
is enabled, triggered by its consumer. At this point, since drvdata is not
yet set and the driver's runtime PM callbacks rely on it, a crash can
occur. To avoid this, set drvdata just after it was allocated.

There is no need to manually track the runtime PM status in the driver.
The pm_runtime_force_suspend() and pm_runtime_force_resume() functions
already call pm_runtime_status_suspended() to check the runtime PM state.
Additionally, avoid calling pm_runtime_put_autosuspend() during the
suspend/resume path, as this would decrease the usage counter of a
potential user that had the ADC open before the suspend/resume cycle.

Update the sysfs interface for sampling frequency and scale attributes.
Replace `scnprintf()` with `sysfs_emit_at()` which is PAGE_SIZE-aware
and recommended for use in sysfs.

In __iodyn_find_io_region(), pcmcia_make_resource() is assigned to
res and used in pci_bus_alloc_resource(). There is a dereference of res
in pci_bus_alloc_resource(), which could lead to a NULL pointer
dereference on failure of pcmcia_make_resource().
Fix this bug by adding a check of res.

ADC calibration might fail because of the noise on reference voltage.
To avoid calibration fail, need to meet the following requirement:
ADC reference voltage Noise < 1.8V * 1/2^ENOB
For the case which the ADC reference voltage on board do not meet
the requirement, still load the calibrated values, so ADC can also
work but maybe not that accurate.

iio_format_list() sets a stride across the val array of 1 for INT
type, and 2 for all others. Add IIO_VAL_CHAR so it also gets a
stride of 1 assuming val is an array of integers with char type
values.
No drivers currently use this, but I found this issue adding an
avail callback for IIO_INFO_THERMOCOUPLE_TYPE for a driver I'm
working on.

One core change removing the 'w' access flag of attributes that don't
have a set routine (and therefore can't be written to) which should
have no practical impact. The big scsi_debug update is caused by
reformatting lots of arrays and the rest of the bug fixes in drivers
are trivial.

Given scan_interval_us and time_per_scan_us are both in usecs, it
makes more sense to use us_to_ktime() helper rather than converting
to nanosecs as needed for ns_to_ktime().

The bd79124 has ADC inputs which can be muxed to be GPIOs. The driver
supports this by registering a GPIO-chip for channels which aren't used
as ADC.
The Kconfig entry does not handle the dependency to GPIOLIB, which
causes errors:
ERROR: modpost: "devm_gpiochip_add_data_with_key" [drivers/iio/adc/rohm-bd79124.ko] undefined!
ERROR: modpost: "gpiochip_get_data" [drivers/iio/adc/rohm-bd79124.ko] undefined!
at linking phase if GPIOLIB is not configured to be used.
Fix this by adding dependency to the GPIOLIB.
