From f30f929fcd6c8d2cae8ec4396534337886e414c0 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 13 Feb 2012 10:25:33 +0100 Subject: [PATCH] staging:iio: Add missing event code extract macros Add macros for extracting whether the event is for a differential channel and the second channel number from the event code. These were the only two fields which did not have such an macro yet.
