Subject: [PATCH AUTOSEL 5.6 156/606] dmaengine: tegra210-adma: Fix an error handling path in 'tegra_adma_probe()'
Date: Mon, 8 Jun 2020 19:04:41 -0400 [thread overview]
Message-ID: <20200608231211.3363633-156-sashal@kernel.org> (raw)
In-Reply-To: <20200608231211.3363633-1-sashal@kernel.org>
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
commit 3a5fd0dbd87853f8bd2ea275a5b3b41d6686e761 upstream.
Commit b53611fb1ce9 ("dmaengine: tegra210-adma: Fix crash during probe")
has moved some code in the probe function and reordered the error handling
path accordingly.
However, a goto has been missed.
Fix it and goto the right label if 'dma_async_device_register()' fails, so
that all resources are released.
Fixes: b53611fb1ce9 ("dmaengine: tegra210-adma: Fix crash during probe")
