Date: Wed, 07 Mar 2007 19:59:52 +0100 From: Brice Goglin <brice@...i.com> To: Jeff Garzik <jeff@...zik.org> CC: netdev@...r.kernel.org Subject: [PATCH 1/4] myri10ge: fix error checking and return value in myri10ge_allocate_rings Fix a missing error check in myri10ge_allocate_rings() and set status to -ENOMEM before all actual allocations so that the error path returns what it should.
