[PATCH] RDMA/bnxt_re: Fix an error code in bnxt_qplib_create_srq()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We should return -ENOMEM if the allocation fails.  (The current code
returns succees).

Fixes: 37cb11acf1f7 ("RDMA/bnxt_re: Add SRQ support for Broadcom adapters")
