From: Cristina Ciocan Date: Tue, 11 Nov 2014 14:07:42 +0000 (+0200) Subject: iio: Fix IIO_EVENT_CODE_EXTRACT_DIR bit mask X-Git-Tag: upstream/snapshot3+hdmi~4^2~42 X-Git-Url: http://review.tizen.org/git/?p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git;a=commitdiff_plain;h=ecee7138d8589cf2975e35a3ede0a1c19e8f8b76 iio: Fix IIO_EVENT_CODE_EXTRACT_DIR bit mask commit ccf54555da9a5e91e454b909ca6a5303c7d6b910 upstream. 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.
