Remove redundant NULL checks before calls to functions that are equivalent to a
no-op when run on a NULL pointer.
These patches were generated by the following semantic patch, and manually
reviewed:
<smpl>
@r@
identifier noop_func;
identifier param;
type T;
@@
noop_func (T *param) {
...
if (!param) return;
...
}
@@
identifier r.noop_func;
expression E;
statement S;
@@
(
- if (E) noop_func(E);
+ noop_func(E);
|
- if (E) { noop_func(E); E = NULL; }
+ noop_func(E);
+ E = NULL;
)
</smpl>
