The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last, which is beneficial
to cultivate a high-quality code.[2]
This issue was found with the help of Coccinelle.

In dma init or reset scene, full buffer is needed for all rx rings. Since
this is very time consuming, split the function to perform initial
allocation without holding the spinlock. This avoids causing excessive

Due to a limitation in available memory, the MT7916 firmware can only
handle either 5 GHz or 6 GHz at a time. It does not support runtime
switching without a full restart.
On older firmware, this accidentally worked to some degree due to missing
checks, but couldn't be supported properly, because it left the 6 GHz
channels uncalibrated.
Newer firmware refuses to start on either band if the passed EEPROM
data indicates support for both.
Deal with this limitation by using a module parameter to specify the
preferred band in case both are supported.

When initializing the network card, unplugging the device will
trigger an -EPROTO error, resulting in a flood of error messages
being printed frantically.
The exception is printed as follows：
mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
mt76x2u 2-2.4:1.0: vendor request req:47 off:9018 failed:-71
...
It will continue to print more than 2000 times for about 5 minutes,
causing the usb device to be unable to be disconnected. During this
period, the usb port cannot recognize the new device because the old
device has not disconnected.
There may be other operating methods that cause -EPROTO, but -EPROTO is
a low-level hardware error. It is unwise to repeat vendor requests
expecting to read correct data. It is a better choice to treat -EPROTO
and -ENODEV the same way.
Similar to commit 9b0f100c1970 ("mt76: usb: process URBs with status
EPROTO properly") do no schedule rx_worker for urb marked with status
set -EPROTO. I also reproduced this situation when plugging and
unplugging the device, and this patch is effective.
Just do not vendor request again for urb marked with status set -EPROTO.

More and more I2C client drivers use debugfs entries and currently they
need to manage a subdir for their files on their own. This means
inconsistent naming for these subdirs and they are scattered all over
the debugfs-tree as well. Not to mention the duplicated code.
Let the I2C core provide and maintain a proper directory per client.
Note: It was considered to save the additional pointer in 'struct
i2c_client' and only provide a subdir when requested via a helper
function. When sketching this approach, more and more corner cases
appeared, though, so the current solution with its simple and unabiguous
code was chosen.

a noisy signal) is sometimes applied. As some devices' (e.g, Lenovo
V15 G4) ACPI tables specify a 400KHz frequency for this device and
some I2C busses (e.g, Designware I2C) default to a 400KHz freq,
force the speed to 100KHz as a workaround.
For future investigation: This problem may be related to the default
HCNT/LCNT values given by some busses' drivers, because they are not
specified in the aforementioned devices' ACPI tables, and because
the device works without issues on Windows at what is expected to be
a 400KHz frequency. The root cause of the issue is not known.

Introduce a new `riic_bus_barrier()` function to verify bus availability
before initiating an I2C transfer. This function enhances the bus
arbitration check by ensuring that the SDA and SCL lines are not held low,
in addition to checking the BBSY flag using `readb_poll_timeout()`.
Previously, only the BBSY flag was checked to determine bus availability.
However, it is possible for the SDA line to remain low even when BBSY = 0.
This new implementation performs an additional check on the SDA and SCL
lines to avoid potential bus contention issues.

Replace the hardcoded `1000000000` with the predefined `NSEC_PER_SEC`
macro for clarity. Simplify the code by introducing a `ns_per_tick`
variable to store `NSEC_PER_SEC / rate`, reducing redundancy and
improving readability.

Simplify the `riic_i2c_probe()` function by using the
`devm_reset_control_get_optional_exclusive_deasserted()` API to request a
deasserted reset line. This eliminates the need to manually deassert the
reset control and the additional cleanup.

Update the `riic_init_hw()` function to use the local `dev` pointer in
calls to `dev_err_probe()`. Previously, `riic_init_hw()` used
`riic->adapter.dev` in error reporting. Since this function is invoked
during the probe phase, the I2C adapter is not yet initialized, leading to
`(null) ...` being printed in error messages. This patch fixes the issue
by consistently using the local `dev` pointer, which points to
`riic->adapter.dev.parent`.

Refactor error handling in the riic_i2c_probe() and riic_init_hw()
functions by replacing multiple dev_err() calls with dev_err_probe().
Additionally, update the riic_init_hw() function to use a local `dev`
pointer instead of `riic->adapter.dev` for dev_err_probe(), as the I2C
adapter is not initialized at this stage. Drop the cast to (unsigned long)
in the riic_init_hw() function when printing the bus frequency, and update
the error message to display the frequency in Hz, improving clarity.
