Subject: [PATCH 3/3] dmaengine: xilinx: Simplify with dev_err_probe()
Date: Fri, 28 Aug 2020 17:26:37 +0200	[thread overview]
Message-ID: <20200828152637.16903-3-krzk@kernel.org> (raw)
In-Reply-To: <20200828152637.16903-1-krzk@kernel.org>

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and the error value gets printed.
