4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Christophe JAILLET <[email protected]> [ Upstream commit 3adfb572f2978a980b250a9e1a56f84f3a031001 ] If alloc_msi_entry() fails, we free resources and set ret = -ENOMEM. However, msix_setup_entries() returns 0 unconditionally. Return the error code instead.
