Hi maintainer,
    Do these warnings need to be resolved?

    The usage of this code is also supported by the standard C language,
    and other drivers also have this usage;

    At the same time, why does the compilation still have [- Wvla] warning
    when adding cflags += no_wvla_cflag in zxdh meson.build

    Thanks

    I will submit a new version that includes Enable assertions failed、
    Enable address sanitizer for undefined checks、Extra memset and cast,
    and [RFC,0/5] net/zxdh: possible changes you submited.

    and sorry for not modifying the cover scan and PVS issue in a timely manner.
    I will make the necessary changes later
