    Subject[PATCH 3.4 003/176] iio: Fix IIO_EVENT_CODE_EXTRACT_DIR bit mask
    Date
    From: Cristina Ciocan <cristina.ciocan@intel.com>

    3.4.107-rc1 review patch. If anyone has any objections, please let me know.

    ------------------


    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.

    Fixes: ade7ef7ba (staging:iio: Differential channel handling)
