    Subject[PATCH 4.16 32/47] iio: adc: select buffer for at91-sama5d2_adc
    Date
    4.16-stable review patch.  If anyone has any objections, please let me know.

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

    From: Eugen Hristev <eugen.hristev@microchip.com>

    commit 76974ef9d1bf397b7bb97892a3b3bc516a1fc2c2 upstream.

    We need to select the buffer code, otherwise we get build errors
    with undefined functions on the trigger and buffer,
    if we select just IIO and then AT91_SAMA5D2_ADC from menuconfig

    This adds a Kconfig 'select' statement like other ADC
    drivers have it already.

    Fixes: 5e1a1da0f8c9 ("iio: adc: at91-sama5d2_adc: add hw trigger and buffer support")
