Similar but not the same, I applied your v2 series, but Jiapeng's patch
is valid:

  1977 static void bnxt_re_remove(struct auxiliary_device *adev)
  1978 {
  1979         struct bnxt_re_en_dev_info *en_info = auxiliary_get_drvdata(adev);
  1980         struct bnxt_en_dev *en_dev;
  1981         struct bnxt_re_dev *rdev;
  1982
  1983         mutex_lock(&bnxt_re_mutex);
  1984         if (!en_info) {
  1985                 mutex_unlock(&bnxt_re_mutex);
  1986                 return;
  1987         }
  1988         en_dev = en_info->en_dev;
  1989         rdev = en_info->rdev;
  1990
  1991         if (rdev)
  1992                 bnxt_re_remove_device(rdev, BNXT_RE_COMPLETE_REMOVE, adev);
  1993         kfree(en_info);
  1994         mutex_unlock(&bnxt_re_mutex);
  1995 }


Thanks
