From e7231491ce6ae2053569166f60835a5594b3c0af Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Fri, 24 Jul 2015 16:28:06 +0300 Subject: [PATCH] tools: iio: print error message when buffer enable fails Running generic_buffer without enabling any channel of the sensor will fail without printing any error message.
