Subject: [PATCH v2 3/5] drivers/dma/amba-pl08x.c: adjust double test

From: Julia Lawall <Julia.Lawall@...6.fr>

Rewrite a duplicated test to test the correct value

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression E;
@@

(
* E
  || ... || E
|
* E
  && ... && E
)
// </smpl>

There is a dstbus field, so it is my guess that that should be tested
instead of testing the srcbus field again.
