staging: rts5208: fix case of bitwise operator on zero in ms.c
If a variable has value 0, then there is no point in combining it with other things with |, as for any
x, 0 | x is just x. The following semantic patch finds this problem.
@@
expression x,e,e1;
statement S;
@@
if (x == 0) {
<... when != x = e1
when != while(...) S
when != for(...;...;...) S
(
* x |= e

* x | e
)

}
