Convert a zero return value on error to a negative one, as returned
elsewhere in the function.
Additionally, converted 1 << 7 to BIT(7) at the suggestion of Lee Jones.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// </smpl>
