Subject: [PATCH 05/16] crypto: atmel-{aes,sha,tdes} - Drop superfluous error message in probe()
Date: Thu, 5 Dec 2019 09:53:51 +0000	[thread overview]
Message-ID: <20191205095326.5094-6-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20191205095326.5094-1-tudor.ambarus@microchip.com>

From: Tudor Ambarus <tudor.ambarus@microchip.com>

In case the probe fails, the device/driver core takes care of printing
the driver name, device name and error code. Drop superfluous error message
at probe.
