From: Jon Mason Date: Thu, 11 Nov 2010 04:25:59 +0000 (+0000) Subject: vxge: Handle errors in vxge_hw_vpath_fw_api X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c3150eac9f2e5f770b09d371f7716540219a46f6;p=openwrt%2Fstaging%2Fblogic.git 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. Signed-off-by: Jon Mason Signed-off-by: Ram Vepa Signed-off-by: David S.
