KASAN reported out of bounds access - cs_dsp_ctl_cache_init_multiple_offsets().
The code uses mock_coeff_template.length_bytes (4 bytes) for register value
allocations. But later, this length is set to 8 bytes which causes
test code failures.
As fix, just remove the lenght override, keeping the original value 4
for all operations.

Commit 3c8260ce7663 ("mtd: rawnand: brcmnand: exec_op implementation")
removed legacy interface functions, breaking < v5.0 controllers support.
In order to fix older controllers we need to add an alternative exec_op
implementation which doesn't rely on low level registers.

sunxi_nfc_hw_ecc_write_chunk
The function sunxi_nfc_hw_ecc_write_chunk() calls the
sunxi_nfc_hw_ecc_write_chunk(), but does not call the configuration
function sunxi_nfc_randomizer_config(). Consequently, the randomization
might not conduct correctly, which will affect the lifespan of NAND flash.
A proper implementation can be found in sunxi_nfc_hw_ecc_write_page_dma().
Add the sunxi_nfc_randomizer_config() to config randomizer.

Signal vt subsystem to redraw console when switching to dummycon
with deferred takeover enabled. Makes the console switch to fbcon
and displays the available output.
With deferred takeover enabled, dummycon acts as the placeholder
until the first output to the console happens. At that point, fbcon
takes over. If the output happens while dummycon is not active, it
cannot inform fbcon. This is the case if the vt subsystem runs in
graphics mode.
A typical graphical boot starts plymouth, a display manager and a
compositor; all while leaving out dummycon. Switching to a text-mode
console leaves the console with dummycon even if a getty terminal
has been started.
Returning true from dummycon's con_switch helper signals the vt
subsystem to redraw the screen. If there's output available dummycon's
con_putc{s} helpers trigger deferred takeover of fbcon, which sets a
display mode and displays the output. If no output is available,
dummycon remains active.

The driver currently uses dev_err for messages that have a very low probability
of being read by the user as the error will probably never happen and the
systems with the RTC probably don't have any user able to read the message.
Moreover, the only user action after getting this message is the restart the
action so drop the level to dev_dbg.

The ocillator on the m41t62 (and other chips of this type) needs
a kickstart upon a failure; the RTC read routine will notice the
oscillator failure and fail reads. This is added in the RTC write
routine; this allows the system to know that the time in the RTC
is accurate. This is following the procedure described in section
3.11 of "https://www.st.com/resource/en/datasheet/m41t62.pdf"

Add a RTC driver for NXP S32G2/S32G3 SoCs.
RTC tracks clock time during system suspend. It can be a wakeup source
for the S32G2/S32G3 SoC based boards.
The RTC module from S32G2/S32G3 is not battery-powered and it is not kept
alive during system reset.

As it's name suggests, parse_eeprom() parses EEPROM data.
This is done by reading data, 16 bits at a time as follows:
for (i = 0; i < 128; i++)
((__le16 *) sromdata)[i] = cpu_to_le16(read_eeprom(np, i));
sromdata is at the same memory location as psrom.
And the type of psrom is a pointer to struct t_SROM.
As can be seen in the loop above, data is stored in sromdata, and thus
psrom, as 16-bit little-endian values. However, the integer fields of
t_SROM are host byte order.
In the case of the led_mode field this results in a but which has been
addressed by commit e7e5ae71831c ("net: dlink: Correct endianness
handling of led_mode").
In the case of the remaining fields, which are updated by this patch,
I do not believe this does not result in any bugs. But it does seem
best to correctly annotate the endianness of integers.

The AF driver assigns reserved MCAM entries (for unicast, broadcast,
etc.) based on the NIXLF number. When a NIXLF is detached, these entries
are disabled.
For example,
PF NIXLF
--------------------
PF0 0
SDP-VF0 1
If the user unbinds both PF0 and SDP-VF0 interfaces and then binds them in
reverse order
PF NIXLF
---------------------
SDP-VF0 0
PF0 1
In this scenario, the PF0 unicast entry is getting corrupted because
the MCAM entry contains stale data (SDP-VF0 ucast data)
This patch resolves the issue by clearing the unicast MCAM entry during
NIXLF detach

When an application sets and enables an alarm on Loongson RTC devices,
the alarm notification fails to propagate to userspace because the
ACPI event handler omits calling rtc_update_irq().
As a result, processes waiting via select() or poll() on RTC device
files fail to receive alarm notifications.
The ACPI interrupt is also triggered multiple times. In loongson_rtc_handler,
we need to clear TOY_MATCH0_REG to resolve this issue.

On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which a
driver can take into account.
On platforms where the offset is stored in a Qualcomm specific UEFI
variable the variables are also accessed in a non-standard way, which
means that the OS cannot assume that the variable service is available
by the time the driver probes.
Use the new 'qcom,uefi-rtc-info' property to determine whether to probe
defer until the UEFI offset becomes available so that the offset can be
used also when the RTC driver is built in or when a dependency of the
UEFI variable driver is built as a module (e.g. the driver for the SCM
interconnects).

The S32 platform has several Watchdog Timer available and tied with a
CPU. The SWT0 is the only one which directly asserts the reset line,
other SWT require an external setup to configure the reset behavior
which is not part of this change.
As a side note, in the NXP documentation, the s32g2 and s32g3
reference manuals refer the watchdog as the 'Software Timer Watchdog'
where the name can be misleading as it is actually a hardware
watchdog.
The maximum watchdog timeout value depends on the clock feeding the
SWT counter which is 32bits wide. On the s32g274-rb2, the clock has a
rate of 51MHz which result on 83 seconds maximum timeout.
The timeout can be specified via the device tree with the usual
existing bindings 'timeout-sec' or via the module param timeout.
The watchdog can be loaded with the 'nowayout' option, preventing the
watchdog to be stopped.
The watchdog can be started at boot time with the 'early-enable'
option, thus letting the watchdog framework to service the watchdog
counter.
The watchdog support the magic character to stop when the userspace
releases the device.

getting ready to enable it, globally.
Use the `DEFINE_RAW_FLEX()` helper for on-stack definitions of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.
So, with these changes, fix the following warning:
