return const struct device * for device_get_binding(const char *name)

[zzzh]

Describe the bug
the definition is now "__syscall const struct device *device_get_binding(const char *name);",
which bring many compile warnings as below, and at last, program can't link

warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
37 | struct device *i2c_dev = device_get_binding(DT_LABEL(I2C2_NODE));

it used to be "__syscall struct device *device_get_binding(const char *name);" and work well in zephyr-2.3

Please also mention any information which could help others to understand

Logs and console output
If applicable, add console logs or other types of debug information
e.g Wireshark capture or Logic analyzer capture (upload in zip archive).
copy-and-paste text and put a code fence (```) before and after, to help
explain the issue. (if unable to obtain text log, add a screenshot)

This is not a bug, you need to use const struct device *dev = device_get_binding(...); now (devices were constified a few releases ago). You can also make use of i2c_dt_spec facilities for I2C devices in particular, as well as take a look at DEVICE_DT_GET(). You'll find many in-tree examples.

I see, Thanks for the help.
