Subject: RDMA/amso1100: Fix error return code
X-Git-Tag: v3.14-rc3~24^2^4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ab576627c8f97c08297d81537be17df161171923;p=kernel%2Fkernel-generic.git

RDMA/amso1100: Fix error return code

Set the return variable to an error code as done elsewhere in the function.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}

// </smpl>
