[PATCH 2/2] soc: ti: knav_qmss_queue: replace IS_ERR_OR_NULL by IS_ERR

[Julia Lawall]

knav_queue_open always returns an ERR_PTR value, never NULL.  This can be
confirmed by unfolding the function calls and conforms to the function's
documentation.  Thus, replace IS_ERR_OR_NULL by IS_ERR in error checks.

The change is made using the following semantic patch:
(http://coccinelle.lip6.fr/)

// <smpl>

expression x;
statement S;

x = knav_queue_open(...);
if (
-   IS_ERR_OR_NULL
+   IS_ERR
    (x)) S
// </smpl>

The patches in this series are completely independent of each other, except
for having been made from the same specification.
