From 98efb70adde96d86df29b4754f265b2c8bba01b2 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 5 Nov 2012 09:56:00 +0000 Subject: [PATCH] staging:iio:ad7887: Use passed in chan spec in ad7887_read_raw Use the passed in chan spec in ad7887_read_raw instead of alawys using the first chan spec entry from the chip info data. Since all channels have the same shift and realbits from a functional point of view it does not matter which chan spec is used, but the patch makes the a bit more clear.
