<id>567ab7727adb81626da7ab4513c15888d0ee2693</id>
<content type='text'>
While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

While touching all these arrays, unify usage of whitespace in the list
terminator.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

<title>nfc: nxp-nci: treat -ENXIO in IRQ thread as no data available</title>

<content type='text'>
The I2C read operation in the IRQ thread may return -ENXIO
when the controller has not yet provided data after asserting IRQ.

IRQ assertion does not guarantee that data is immediately
available on the I2C bus. In such cases, the read request may
be NACKed, resulting in -ENXIO.

Treat this condition as "no data available yet" and log it at
debug level instead of reporting it as a read failure.

This avoids misleading error messages during normal operation.

Some ACPI-based platforms report incorrect IRQ trigger types (e.g.
IRQF_TRIGGER_HIGH), which can lead to interrupt storms.

Use the historically working rising-edge trigger on ACPI systems to
avoid this regression.

Device Tree-based systems continue to use the firmware-provided
trigger type.

Replace strcpy() with strscpy() which limits the copy to the size of
the destination buffer. Since fw_info-&gt;name is an array, the
two-argument variant of strscpy() is used - the compiler deduces
the buffer size automatically.

This is a defensive cleanup replacing the deprecated strcpy()
with the preferred strscpy().

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.
