In 4.19 and 4.20 just works, but when I tried in 5.0.x this happens:

/home/admin/downloads/rtl8723de-4.15-up/os_dep/linux/rtw_android.c: In the 'rtw_android_priv_cmd' function:
/home/admin/downloads/rtl8723de-4.15-up/os_dep/linux/rtw_android.c:629:62: error: the macro «access_ok» passed 3 arguments, but only takes 2
  if (! access_ok (VERIFY_READ, priv_cmd.buf, priv_cmd.total_len)) {
                                                              ^
