dmaengine: dw: drop useless LIST_HEAD
Drop LIST_HEAD where the variable it declares is never used.
Commit ab703f818ac3 ("dmaengine: dw: lazy allocation of dma
descriptors") removed the uses, but not the declaration.
The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
... when != x
// </smpl>
Fixes: ab703f818ac3 ("dmaengine: dw: lazy allocation of dma descriptors")
