Subject: [PATCH 4.19 68/79] dmaengine: ti: omap-dma: Add cleanup in omap_dma_probe()
Date: Fri, 20 Sep 2019 00:03:53 +0200 [thread overview]
Message-ID: <20190919214813.612818080@linuxfoundation.org> (raw)
In-Reply-To: <20190919214807.612593061@linuxfoundation.org>
From: Wenwen Wang <wenwen@cs.uga.edu>
[ Upstream commit 962411b05a6d3342aa649e39cda1704c1fc042c6 ]
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.
