From 3aa58cb51318e329d203857f7a191678e60bb714 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 7 Jan 2024 11:02:04 +0100 Subject: [PATCH] dmaengine: fsl-qdma: Fix a memory leak related to the queue command DMA This dma_alloc_coherent() is undone neither in the remove function, nor in the error handling path of fsl_qdma_probe(). Switch to the managed version to fix both issues.
