dmaengine: dw: drop useless LIST_HEAD
Drop LIST_HEAD where the variable it declares is never used. Commitab703f818a
("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:ab703f818a
