Description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/hns: Fix warning in poll cq direct mode

CQs allocated by ib_alloc_cq() always have a comp_handler. Though in direct mode this handler is never expected to be called, it is still called when the driver is reset, triggering the following WARN_ONCE():
