Julia Lawall 80d02d2736 drivers/w1/masters/omap_hdq.c: add missing clk_put ... This code makes two calls to clk_get, then test both return values and fails if either failed. The problem is that in the first inner if, where the first call to clk_get has failed, it don't know if the second call has failed as well. So it don't know whether clk_get should be called on the result of the second call. Of course, it would be possible to test that value again. A simpler solution is just to test the result of calling clk_get directly after each call. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ position p1,p2; expression e; statement S; @@ e = clk_get@p1(...) ... if@p2 (IS_ERR(e)) S @@ expression e; statement S; identifier l; position r.p1, p2 != r.p2; @@ *e = clk_get@p1(...) ... when != clk_put(e) *if@p2 (...) { ... when != clk_put(e) * return ...; }// </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Acked-by: Tony Lindgren <tony@atomide.com> Acked-by: Amit Kucheria <amit.kucheria@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2011-02-11 16:12:20 -08:00
