| |
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>
