From: Roland Dreier Date: Thu, 1 Mar 2007 21:17:14 +0000 (-0800) Subject: IB/mthca: Fix error path in mthca_alloc_memfree() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=88171cfed5810a2354eb1977883589a05ce8d304;p=linux-beck.git IB/mthca: Fix error path in mthca_alloc_memfree() The garbled logic in mthca_alloc_memfree() causes it to return 0, even if it fails to allocate all doorbell records. Fix it to return -ENOMEM when it fails.
