From c6d01179bfee3048cce98fe303d7265faa3861a7 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Tue, 5 Feb 2008 13:13:15 +1100 Subject: [PATCH] [POWERPC] Avoid possible extra of_node_put in axon_msi.c I got this warning from gcc: arch/powerpc/platforms/cell/axon_msi.c:118: warning: 'tmp' may be used uninitialized in this function Which turns out to be a false positive, but pointed out that it was possible for the error path in find_msi_translator() to do an extra of_node_put on a node. This fixes it by localising the ref counting a bit. As a side effect, the warning goes away.
