Subject: RDMA/rdmavt: Fix error code in rvt_create_qp()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=663991f32857b3b63c94c97de9dbb0ec8600144f;p=linux.git

RDMA/rdmavt: Fix error code in rvt_create_qp()

Return negative -ENOMEM instead of positive ENOMEM.  Returning a postive
value will cause an Oops because it becomes an ERR_PTR() in the
create_qp() function.

Fixes: 514aee660df4 ("RDMA: Globally allocate and release QP memory")
