Subject: [PATCH 13/14] iio: sensors-core: st: Clean-up error handling in st_sensors_init_sensor()
Date: Mon,  9 Sep 2013 11:10:09 +0100	[thread overview]
Message-ID: <1378721410-30937-14-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1378721410-30937-1-git-send-email-lee.jones@linaro.org>

Strip out all those unnecessary gotos and just return the error right away.

Aids to simplicity and reduces code.
