From 9bef4929fa21477d44b4934d02296c4d0126dd40 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 14 Jun 2022 19:47:59 +0100 Subject: [PATCH] dmaengine: fsl-edma: remove redundant assignment to pointer last_sg The pointer last_sg is being assigned a value at the start of a loop however it is never read and is being re-assigned later on in both brances of an if-statement. The assignment is redundant and can be removed.
