Subject: [PATCH 1/5] i2c: i.MX: Do not call i2c_fsl_bus_busy twice
Date: Wed, 27 Feb 2019 09:19:41 +0100	[thread overview]
Message-ID: <20190227081945.27001-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20190227081945.27001-1-s.hauer@pengutronix.de>

In i2c_fsl_stop() we call i2c_fsl_bus_busy() a second time when it
fails. If it fails once it won't succeed the second time, so drop
the second call.
