Function clk_get, defined just below this code, returns ERR_PTR not NULL in an error case. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier f; @@ f(...) { ... return ERR_PTR(...); } @@ identifier r.f, fld; expression x; statement S1,S2; @@ x = f(...) ... when != IS_ERR(x) ( if (IS_ERR(x) ||...) S1 else S2 | *x->fld ) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- arch/arm/mach-at91/clock.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/mach-at91/clock.c b/arch/arm/mach-at91/clock.c index 9113da6..c9ee6d0 100644 --- a/arch/arm/mach-at91/clock.c +++ b/arch/arm/mach-at91/clock.c @@ -224,7 +224,7 @@ void __init at91_clock_associate(const char *id, struct device *dev, const char { struct clk *clk = clk_get(NULL, id); - if (!dev || !clk || !IS_ERR(clk_get(dev, func))) + if (!dev || IS_ERR(clk) || !IS_ERR(clk_get(dev, func))) return; clk->function = func; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
