Subject: [PATCH] dmaengine: pl330: drop useless LIST_HEAD
Git-commit: 4f194969c3b01ab080d38114feb09be05b16d7c3
Patch-mainline: v5.1-rc1
References: bsc#1051510
Drop LIST_HEAD where the variable it declares is never used.
The variable has not been used since the function was introduced
in 740aa95703c5 ("dmaengine: pl330: Split device_control").
The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
... when != x
// </smpl>
Fixes: 740aa95703c5 ("dmaengine: pl330: Split device_control")
