From 91ca1a8c584f55857b1f6ab20a1d3a1ce7a559bb Mon Sep 17 00:00:00 2001 From: Pan Bian Date: Sat, 3 Dec 2016 21:44:30 +0800 Subject: [PATCH] staging: iio: cdc: fix improper return value 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".
