Subject: [PATCH 1/6] gpio: xgene: remove redundant error message
Date: Wed,  2 Oct 2019 19:02:44 +0200	[thread overview]
Message-ID: <20191002170249.17366-2-brgl@bgdev.pl> (raw)
In-Reply-To: <20191002170249.17366-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

There's no need to emit an error message on probe failure unless we're
printing some meaningful info. Otherwise the core driver code will
inform us about a probe error.
