From eb5685f0de4702e44a8b262f1acaea52ef99271a Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Fri, 30 May 2014 11:35:53 -0600 Subject: vfio/pci: Fix unchecked return value There's nothing we can do different if pci_load_and_free_saved_state() fails, other than maybe print some log message, but the actual re-load of the state is an unnecessary step here since we've only just saved it. We can cleanup a coverity warning and eliminate the unnecessary step by freeing the state ourselves.
