Subject: staging: tidspbridge: adjust error return code (bugfix)
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ff11917d4f1b03d19dcc3c5f3ad813e428c21f40;p=deliverable%2Flinux.git

staging: tidspbridge: adjust error return code (bugfix)

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>
