Because both MT7920 and MT7921 use the same chip ID.
We use the 8th bit of fw_flavor to distingush MT7920.
The original patch made a mistake to check whole fw_flavor,
that makes the condition both true (dev_id == 0x7961 && fw_flavor),
and makes MT7921 flow wrong.
In this patch, we correct the flow to get the 8th bit value for MT7920.
And the patch is verified pass with both MT7920 and MT7921.

Like the bcm43430a0 the bcm43455 BT does not support the 0xfc45 command
to set the UART clock to 48 MHz and because of this it does not work
at 4000000 baud.
These chips are found on ACPI/x86 devices where the operating baudrate
does not come from the firmware but is hardcoded at 4000000, which does
not work.
Make the driver_data for the "BCM2EA4" ACPI HID which is used for
the bcm43455 BT point to bcm43430_device_data which limits the baudrate
to 2000000.

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally.
There are currently a couple of objects (`req` and `rsp`), in a couple
of structures, that contain flexible structures (`struct l2cap_ecred_conn_req`
and `struct l2cap_ecred_conn_rsp`), for example:
struct l2cap_ecred_rsp_data {
struct {
struct l2cap_ecred_conn_rsp rsp;
__le16 scid[L2CAP_ECRED_MAX_CID];
} __packed pdu;
int count;
};
in the struct above, `struct l2cap_ecred_conn_rsp` is a flexible
structure:
struct l2cap_ecred_conn_rsp {
__le16 mtu;
__le16 mps;
__le16 credits;
__le16 result;
__le16 dcid[];
};
So, in order to avoid ending up with a flexible-array member in the
middle of another structure, we use the `struct_group_tagged()` (and
`__struct_group()` when the flexible structure is `__packed`) helper
to separate the flexible array from the rest of the members in the
flexible structure:
struct l2cap_ecred_conn_rsp {
struct_group_tagged(l2cap_ecred_conn_rsp_hdr, hdr,
... the rest of members
);
__le16 dcid[];
};
With the change described above, we now declare objects of the type of
the tagged struct, in this example `struct l2cap_ecred_conn_rsp_hdr`,
without embedding flexible arrays in the middle of other structures:
struct l2cap_ecred_rsp_data {
struct {
struct l2cap_ecred_conn_rsp_hdr rsp;
__le16 scid[L2CAP_ECRED_MAX_CID];
} __packed pdu;
int count;
};
Also, when the flexible-array member needs to be accessed, we use
`container_of()` to retrieve a pointer to the flexible structure.
We also use the `DEFINE_RAW_FLEX()` helper for a couple of on-stack
definitions of a flexible structure where the size of the flexible-array
member is known at compile-time.
So, with these changes, fix the following warnings:
net/bluetooth/l2cap_core.c:1260:45: warning: structure containing a
flexible array member is not at the end of another structure
[-Wflex-array-member-not-at-end]

In case of a Broadcast Source that has PA enabled but no active BIG,
a Broadcast Sink needs to establish PA sync and parse BASE from PA
reports.
This commit moves the allocation of a PA sync hcon from the BIGInfo
advertising report event to the PA sync established event. After the
first complete PA report, the hcon is notified to the ISO layer. A
child socket is allocated and enqueued in the parent's accept queue.
BIGInfo reports also need to be processed, to extract the encryption
field and inform userspace. After the first BIGInfo report is received,
the PA sync hcon is notified again to the ISO layer. Since a socket will
be found this time, the socket state will transition to BT_CONNECTED and
the userspace will be woken up using sk_state_change.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The blamed commit started to use the ptp workqueue to get the second
part of the timestamp. And when the port was set down, then this
workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING
is not enabled, then the ptp_clock is not initialized so then it would
crash when it would try to access the delayed work.
So then basically by setting up and then down the port, it would crash.
The fix consists in checking if the ptp_clock is initialized and only
then cancel the delayed work.

Dell All In One (AIO) models released after 2017 use a backlight controller
board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
Instead of having a separate ACPI device with an UartSerialBusV2() resource
to model the backlight-controller, which would be the standard way to do
this.
The acpi_quirk_skip_serdev_enumeration() has special handling for this
and it will make the serial port code create a serdev controller device
for the UART instead of a /dev/ttyS0 char-dev. It will also create
a dell-uart-backlight driver platform device for this driver to bind too.
This new kernel module contains 2 drivers for this:
1. A simple platform driver which creates the actual serdev device
(with the serdev controller device as parent)
2. A serdev driver for the created serdev device which exports
the backlight functionality uses a standard backlight class device.

The Xiaomi [Mi]Pad 2 has 3 menu / home / back capacitive touch-buttons
on its bottom bezel. These are backlit by LEDs attached to a TPS61158 LED
controller which is controlled by the "pwm_soc_lpss_2" PWM output.
Create a LED class device for this, using the new input-events trigger
as default trigger so that the buttons automatically light up on any
input activity.
Note alternatively a "leds_pwm" platform device could be created together
with the necessary fwnode_s_ and a fwnode link to the PWM controller.
There are 2 downsides to this approach:
1. The code would still need to pwm_get() the PWM controller to get/attach
a fwnode for the PWM controller fwnode link and setting up the necessary
fwnodes is non-trivial. So this would likely require more code then simply
registering the LED class device directly.
2. Currently the leds_pwm driver and its devicetree bindings do not support
limiting the maximum dutycycle to less then 100% which is required in this
case (the leds_pwm driver can probably be extended to allow this).
