From c9c5d9feef86debee4d8e77a738ad86877cf371a Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Sat, 17 Jun 2006 20:37:41 -0700 Subject: [PATCH] IB/mthca: Fix memory leak on modify_qp error paths Some error paths after the mthca_alloc_mailbox() call in mthca_modify_qp() just do a "return -EINVAL" without freeing the mailbox. Convert these returns to "goto out" to avoid leaking the mailbox storage.
