From e59d81e9173ae4b5037a81a08b1c5a6915b333e3 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 16 May 2023 14:55:35 +0200 Subject: [PATCH] dmaengine: ste_dma40: Pass dev to OF function The OF platform data population function only wants to use struct device *dev, so pass that instead. This change makes the compiler realize that the local platform data variable is unused, so drop that too.
