From ccf54555da9a5e91e454b909ca6a5303c7d6b910 Mon Sep 17 00:00:00 2001 From: Cristina Ciocan Date: Tue, 11 Nov 2014 16:07:42 +0200 Subject: [PATCH] iio: Fix IIO_EVENT_CODE_EXTRACT_DIR bit mask The direction field is set on 7 bits, thus we need to AND it with 0111 111 mask in order to retrieve it, that is 0x7F, not 0xCF as it is now.
