Message-Id: <1444258032-41476-18-git-send-email-jeffrey.t.kirsher@intel.com> Date: Wed, 7 Oct 2015 15:47:11 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Mitch Williams <mitch.a.williams@...el.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 17/18] i40evf: propagate interrupt allocation failure From: Mitch Williams <mitch.a.williams@...el.com> Lower level functions are properly reporting errors, and higher-level functions are correctly responding to errors, but the errors aren't actually getting through. Typically, the middle-manager function seems to want to shield its boss from any bad news. This change fixes a panic if the driver is unable to enable MSI-X or is unable to acquire enough vectors.
