[POWERPC] arch/powerpc/platforms/pseries: Add missing of_node_put
Of_get_parent and of_find_compatible_node do an of_node_get, and thus a corresponding of_code_put is needed in the error case. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * E = \(of_get_parent\|of_find_compatible_node\)(...); if (E == NULL) S ... when != of_node_put(...,(T1)E,...) when != if (E != NULL) { ... of_node_put(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != of_node_put(...,(T2)E,...) when != if (E != NULL) { ... of_node_put(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Stephen Rothwell <sfr@canb.auug.org.au> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Kumar Gala <galak@gate.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
