Date: Thu, 4 Nov 2010 17:51:58 -0500 From: Jon Mason <jon.mason@...r.com> To: David Miller <davem@...emloft.net> Cc: netdev@...r.kernel.org, Sivakumar Subramani <sivakumar.subramani@...r.com>, Sreenivasa Honnur <sreenivasa.honnur@...r.com>, Ram Vepa <ram.vepa@...r.com> Subject: [PATCH 07/11] vxge: Handle errors in vxge_hw_vpath_fw_api Propagate the return code of the call to vxge_hw_vpath_fw_api and __vxge_hw_vpath_pci_func_mode_get. This enables the proper handling of error conditions when querying the function mode of the device during probe.
