Subject: [PATCH] RDMA/core: Fix use of logical OR in get_new_pps
Date: Mon, 17 Feb 2020 13:43:18 -0700	[thread overview]
Message-ID: <20200217204318.13609-1-natechancellor@gmail.com> (raw)

Clang warns:

../drivers/infiniband/core/security.c:351:41: warning: converting the
enum constant to a boolean [-Wint-in-bool-context]
        if (!(qp_attr_mask & (IB_QP_PKEY_INDEX || IB_QP_PORT)) && qp_pps) {
                                               ^
1 warning generated.

A bitwise OR should have been used instead.

Fixes: 1dd017882e01 ("RDMA/core: Fix protection fault in get_pkey_idx_qp_list")
