-------- Mensagem original -------- Assunto: [PATCH 5/5] drivers/media/platform/omap3isp/isp.c: fix error return code Data: Tue, 4 Sep 2012 18:14:25 +0200 De: Peter Senna Tschudin <peter.senna@gmail.com> Para: Mauro Carvalho Chehab <mchehab@infradead.org> CC: kernel-janitors@vger.kernel.org, Julia.Lawall@lip6.fr, linux-media@vger.kernel.org, linux-kernel@vger.kernel.org
From: Peter Senna Tschudin <peter.senna@gmail.com>
Convert a nonnegative error return code to a negative one, as returned elsewhere in the function.
A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; }
// </smpl>
