drivers/char/ppdev.c: put gotten port value
parport_find_number() calls parport_get_port() on its result, so there
should be a corresponding call to parport_put_port() before dropping the
reference. Similar code is found in the function register_device() in the
same file.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@exists@
local idexpression struct parport * x;
expression ra,rr;
statement S1,S2;
@@
x = parport_find_number(...)
... when != x = rr
when any
when != parport_put_port(x,...)
when != if (...) { ... parport_put_port(x,...) ...}
(
if(<+...x...+>) S1 else S2
|
if(...) { ... when != x = ra
when forall
when != parport_put_port(x,...)
*return...;
}
)
// </smpl>
