[PATCH v3 03/10] crypto: hisilicon/qm - fix print frequence in hisi_qp_send
From: Yang Shen <shenyang39@huawei.com>
Date: 2020-07-23 07:21:58
Subsystem:
crypto api, hisilicon qm driver, the rest · Maintainers:
Herbert Xu, "David S. Miller", Weili Qian, Zhou Wang, Linus Torvalds
Requests will be sent continuously as resetting, which will cause 'printk'
flooding. Using 'dev_info_ratelimited' can solve this problem well.
