Xie XiuQi, 你好 已按要求提交issue，并更新到patch中
另外，我这边还有近100个CWE代码漏洞补丁，都通过提交issue，关联patch的 这种方式提交吗？
嗯。也是发到邮件列表，可以按照 pachset 发。
issue 不必每个 patch 提一个，可以多个提一个 issue

格式我稍微调整了一下，你可以参照这个再重发一下。

dahua inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4HDHZ CVE: NA
Declaring variable "tuner_status" without initializer. Using uninitialized value "tuner_status" when calling "*fe_tuner_ops->get_status". (The function pointer resolves to "cx24113_get_status".)

mainline-inclusion
该补丁是你自己开发的，不是主线 backport 的，不要标成 mainline inclusion, 你可以写成 driver inclusioin, 或者 dahua inclusion 都可以。
from mainline-openEuler-22.03-LTS
自己开发的补丁，不需要这一行。
category: bugfix Subject: [PATCH openEuler-22.03-LTS] fix CWE-457 bug#1
Subject 是补丁标题，不是标在这里的。使用 git format-patch 生成的补丁， 应该格式就 OK 了。
Declaring variable "tuner_status" without initializer. Using uninitialized value "tuner_status" when calling "*fe_tuner_ops->get_status". (The function pointer resolves to "cx24113_get_status".)
该补丁，确实 fix 了这特场景的初始化问题。 我看社区主线也有这个问。
建议也同时往社区发一下。
这个补丁格式修改一下，再往openEuler发一版本吧。
