Subject: [lm-sensors] [PATCH v2] hwmon: (ads7871) Fix ads7871_probe error
Date: Tue, 17 Aug 2010 12:41:24 +0000	[thread overview]
Message-ID: <1282048884.2626.2.camel@phoenix> (raw)

This patch moves hwmon_device_register() to the end of ads7871_probe().
So we can make sure the device exists and is properly initialized
before the device is exposed to user-space.
