V4L/DVB (13685): Correct code taking the size of a pointer
sizeof(print_buf) is just the size of the pointer. Change it to the size used in the allocation of print_buf earlier in the same function. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // </smpl> Cc: Janne Grunau <j@jannau.net> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
