From 700e982f28f5e13cef8eea93ac8c6702f699d894 Mon Sep 17 00:00:00 2001 From: Jan Glauber Date: Thu, 26 Mar 2009 15:24:27 +0100 Subject: [PATCH] [S390] qdio: call qdio_free also if qdio_shutdown fails qdio_cleanup is a wrapper function that should call qdio_shutdown and qdio_free. qdio_free was not called if an error occured in qdio_shutdown resulting in a missing free of allocated resources. Call qdio_free regardless of the return value of qdio_shutdown.
