In mISDN/dsp_cmx.c, an else is added between the original if branch and the following statement, in line with the code following it. Without this change, the first assignment to dsp->rx_W has no useful effect. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @r disable braces4@ position p1,p2; statement S1,S2; @@ ( if (...) { ... } | if (...)
