Subject: [PATCH] dmaengine: imx-sdma: fix incorrect conversion to readl_relaxed_poll_timeout_atomic()
Date: Sat, 22 Jun 2019 19:02:48 +0100	[thread overview]
Message-ID: <E1hekLg-0002hJ-Jg@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20190622165318.bgyun52hssqmdv4n@shell.armlinux.org.uk>

When imx-sdma was converted to use readl_relaxed_poll_timeout_atomic(),
the termination condition was inverted.  Fix this.
