If these helpers receive the 'const struct device' pointer, then the const qualifier will get dropped, leading to below warning: warning: passing argument 1 of ‘to_serdev_device_driver’ discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] This is not an issue as of now, but with the future commits adding serdev device based driver matching, this warning will get triggered. Hence, convert these helpers to macros so that the qualifier get preserved and also use container_of_const() as container_of() is deprecated.
