From 131e97d3faf2df29a6a488b94890481351f18aea Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Wed, 26 Nov 2014 18:55:10 +0100 Subject: [PATCH] staging:iio:sca3000: Register same channels for device and buffer In preparation for moving the buffer registration to the core make sure to register the same channel array for the device and the buffer. Currently the temperature channel is not registered for the buffer, setting its scan index to -1 will make sure that it is skipped for the buffer.
