From dcae29be4fba85cc9965511f5c112bd08892b1cb Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Fri, 13 Sep 2013 08:23:20 +0000 Subject: [PATCH] i40e: convert ret to aq_ret When calling admin queue functions the driver should use aq_ret variable to help make clear that the return value is not a regular return variable. This allows for clean up of the return types that were previously converted to int.
