From 1c297a66654a3295ae87e2b7f3724d214eb2b5ec Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Mon, 1 Jul 2013 15:20:00 +0100 Subject: [PATCH] iio: Fix iio_channel_has_info Since the info_mask split, iio_channel_has_info() is not working correctly. info_mask_separate and info_mask_shared_by_type, it is not possible to compare them directly with the iio_chan_info_enum enum. Correct that bit using the BIT() macro.
