From: Chengchang Tang tangchengchang@huawei.com
mainline inclusion from mainline-v5.18-rc1 commit 0018ed4bb07f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5A9XK CVE: NA
reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?id=001...
The value of the function parameter "timeout" is unique. Therefore, it is unnecessary to specify the parameter "timeout" value each time. So remove it.
