Message-Id: <1407492475-26283-9-git-send-email-Julia.Lawall@lip6.fr> Date: Fri, 8 Aug 2014 12:07:50 +0200 From: Julia Lawall <Julia.Lawall@...6.fr> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: kernel-janitors@...r.kernel.org, devel@...verdev.osuosl.org, linux-kernel@...r.kernel.org, Uwe Kleine-König <u.kleine-koenig@...gutronix.de> Subject: [PATCH 9/14] imx-drm: imx-drm-core: delete unneeded test before of_node_put From: Julia Lawall <Julia.Lawall@...6.fr> Of_node_put supports NULL as its argument, so the initial test is not necessary. Suggested by Uwe Kleine-König. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e; @@ -if (e) of_node_put(e); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr> --- drivers/staging/imx-drm/imx-drm-core.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/staging/imx-drm/imx-drm-core.c b/drivers/staging/imx-drm/imx-drm-core.c index 6b22106..1852300 100644 --- a/drivers/staging/imx-drm/imx-drm-core.c +++ b/drivers/staging/imx-drm/imx-drm-core.c @@ -471,8 +471,7 @@ int imx_drm_encoder_parse_of(struct drm_device *drm, crtc_mask |= mask; } - if (ep) - of_node_put(ep); + of_node_put(ep); if (i == 0) return -ENOENT; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
