Subject: [PATCH 2/2] iio: magnetometer: iio-mux: Simplify with dev_err_probe()
Date: Wed, 26 Aug 2020 18:15:39 +0200	[thread overview]
Message-ID: <20200826161539.20788-2-krzk@kernel.org> (raw)
In-Reply-To: <20200826161539.20788-1-krzk@kernel.org>

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