From 1438cde8fe9cb709b569f5829c4c892c0f3f15b3 Mon Sep 17 00:00:00 2001 From: Yu Kuai Date: Thu, 18 Jun 2020 21:01:10 +0800 Subject: dmaengine: ti: k3-udma: add missing put_device() call in of_xudma_dev_get() if of_find_device_by_node() succeed and platform_get_drvdata() failed, of_xudma_dev_get() will return without put_device(), which will leak the memory.
