V4L/DVB: drivers/media/video/tlg2300: Use kmemdup
Use kmemdup when some other buffer is immediately copied into the allocated region. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...) S - memcpy(to, from, size); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Douglas Schilling Landgraf <dougsland@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
