2010-08-12	mfd: Fix davinci memory leak	Julia Lawall	1	-2/+4
	Error handling code following a kmalloc should free the allocated data. The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S; expression E; identifier f,f1,l; position p1,p2; expression ptr != NULL; @@ x@p1 = \(kmalloc\\|kzalloc\\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } ( x->f1 = E \| (x->f1 == NULL \|\| ...) \| f(...,x->f1,...) ) ...> ( return \(0\\|<+...x...+>\\|ptr\); \| return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print " file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
