Subject: [PATCH 03/11] mmc: dw_mmc-zx: Simplify with dev_err_probe()
Date: Wed, 2 Sep 2020 21:36:50 +0200 [thread overview]
Message-ID: <20200902193658.20539-4-krzk@kernel.org> (raw)
In-Reply-To: <20200902193658.20539-1-krzk@kernel.org>
Common pattern of handling deferred probe can be simplified with
dev_err_probe(). Less code and the error value gets printed.
