Subject: [PATCH AUTOSEL for 3.18 10/16] staging: iio: cdc: fix improper return
 value

From: Pan Bian <bianpan2016@....com>

[ Upstream commit 91ca1a8c584f55857b1f6ab20a1d3a1ce7a559bb ]

At the end of function ad7150_write_event_config(), directly returns 0.
As a result, the errors will be ignored by the callers. It may be better
to return variable "ret".
