[PATCH 1/1] ibmveth: Fix oops on request_irq failure
From: Brian King <hidden>
Date: 2011-09-28 15:34:05
If request_irq fails, the ibmveth driver will overwrite the rc and end up returning a successful rc on its open function, resulting in an oops later when a packet gets sent and buffers are not allocated due to the failed open.
