Subject: [PATCH 1/2] iio: magnetometer: mag3110: Simplify with dev_err_probe()
Date: Wed, 26 Aug 2020 18:15:38 +0200	[thread overview]
Message-ID: <20200826161539.20788-1-krzk@kernel.org> (raw)

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