Nicolas Palix 44ea9c809d drivers/macintosh: Add missing of_node_put in therm_adt746x.c ... of_node_put is needed before discarding a value received from of_find_node_by_name, eg in error handling code or when the device node is no longer used. The semantic match that catches the bug is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression struct device_node *n; position p1, p2; struct device_node *n1; statement S; identifier f; expression E; expression *ptr != NULL; @@ n@p1 = of_find_node_by_name(...) ... if (!n) S ... when != of_node_put(n) when != n1 = f(n,...) when != E = n when any when strict ( return \(0\|<+...n...+>\|ptr\); | return@p2 ...; | of_node_put(n); | n1 = f(n,...) | E = n ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s of_find_node_by_name %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Nicolas Palix <npalix@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2009-01-06 15:59:18 -08:00
