Subject: [PATCH] iio: Fix iio_buffer_register stub signature
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Match the iio_buffer_register stub signature up to the real function and make
the second parameter const. This fixes a the following warnings if
CONFIG_IIO_BUFFER is disabled:
drivers/staging/iio/accel/adis16201_core.c: In function ‘adis16201_probe’:
