From 962411b05a6d3342aa649e39cda1704c1fc042c6 Mon Sep 17 00:00:00 2001 From: Wenwen Wang Date: Fri, 16 Aug 2019 01:56:08 -0500 Subject: dmaengine: ti: omap-dma: Add cleanup in omap_dma_probe() If devm_request_irq() fails to disable all interrupts, no cleanup is performed before retuning the error. To fix this issue, invoke omap_dma_free() to do the cleanup.
