[PATCH 4/4] staging: tidspbridge: adjust error return code (bugfix)

[Julia Lawall <julia.lawall@lip6.fr>]

From: Julia Lawall <Julia.Lawall@lip6.fr>

The variable status is initialized to either 0 or an error code.  Return
status to propagate the error value.

A simplified version of the semantic patch that fixes this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
type T;
identifier i;
constant c;
@@

-T i;
<... when != i
-i = c;
...>
// </smpl>

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>

Most remove functions only return 0, as this one did before the change.  So
perhaps the correct solution is to remove the status variable?
