RDMA/core: Fix use of logical OR in get_new_pps
Browse files Browse the repository at this point in the history
[ Upstream commit 4ca501d ]

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: 1dd0178 ("RDMA/core: Fix protection fault in get_pkey_idx_qp_list")
