Subject: [PATCH v3 04/18] iio: adc: exynos_adc: Simplify with dev_err_probe()
Date: Sat, 29 Aug 2020 08:47:12 +0200	[thread overview]
Message-ID: <20200829064726.26268-4-krzk@kernel.org> (raw)
In-Reply-To: <20200829064726.26268-1-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.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com>

Changes since v2:
1. Wrap dev_err_probe() lines at 80 character

Changes since v1:
1. Wrap dev_err_probe() lines at 100 character
