Its replacement with a struct assignment is prefered because it's type-safe and much easier to read. Found by coccinelle. Hand patched and reviewed. Tested by compilation only. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // Signed-off-by: Peter Senna Tschudin Signed-off-by: Ezequiel Garcia --- drivers/media/radio/radio-wl1273.c | 3 +-- 1 files changed, 1 insertions(+), 2 deletions(-) diff --git a/drivers/media/radio/radio-wl1273.c b/drivers/media/radio/radio-wl1273.c index 9b0c9fa..6e55e93 100644 --- a/drivers/media/radio/radio-wl1273.c +++ b/drivers/media/radio/radio-wl1273.c @@ -2084,8 +2084,7 @@ static int __devinit wl1273_fm_radio_probe(struct platform_device *pdev) } /* V4L2 configuration */ - memcpy(&radio->videodev, &wl1273_viddev_template, - sizeof(wl1273_viddev_template)); + radio->videodev = wl1273_viddev_template; radio->videodev.v4l2_dev = &radio->v4l2dev; -- 1.7.4.4
