20 Sep '23

From: Yu'an Wang <wangyuan46(a)huawei.com> driver inclusion category: bugfix bugzilla:https://gitee.com/openeuler/kernel/issues/I830AI CVE: NA -------------------------------- Before initializing the device, reset the device to clear the residual data to prevent unexpected problems, such as reboot scene, which may maintain device state before reboot.
