mainline inclusion from mainline-v5.15-rc1 commit 5f22a80f32deed391011f7ab3ce8951ea89282f8 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4BY3P CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
The param msg_q is redundant, copy &req->msg to hdev->arq.msg_q[hdev->arq.tail] directly makes code clean. So removes the redundant param msg_q.
