From: Weili Qian <qianweili@huawei.com> driver inclusion category: cleanup bugzilla: https://gitee.com/openeuler/kernel/issues/ICESZH CVE: NA ---------------------------------------------------------------------- In uacce_free_dma_buffers(), if the loop is executed many times, many duplicate logs will be printed when the WARN_ON condition is met. Therefore, use WARN_ON_ONCE instead of WARN_ON.
