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>
