Subject: Re: [iio:togreg 15/46] drivers/iio/kfifo_buf.c:160:2: error: unknown field 'data_available' specified in initializer
Date: Mon, 06 Jan 2014 19:07:07 +0100 [thread overview]
Message-ID: <52CAF0CB.7090404@metafoo.de> (raw)
In-Reply-To: <52caeebf.H+6mzRdjL24A0dvf%fengguang.wu@intel.com>
I think the faulty commit is this one c9190956 ("
staging:iio:dummy fix kfifo_buf kconfig dependency issue if kfifo modular
and buffer enabled for built in dummy driver"). It selects IIO_KFIFO_BUF
without also selecting IIO_BUFFER or depending on IIO_BUFFER.
