Subject: [PATCH 5/6] gpio: pisosr: Simplify with dev_err_probe()
Date: Thu, 27 Aug 2020 22:08:26 +0200 [thread overview]
Message-ID: <20200827200827.26462-5-krzk@kernel.org> (raw)
In-Reply-To: <20200827200827.26462-1-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>
