iio:buffer: Free active scan mask in iio_disable_all_buffers()iio-fixes-for-3.12c
Usually the active scan mask is freed in __iio_update_buffers() when the buffer is disabled. But when the device is still sampling when it is removed we'll end up disabling the buffers in iio_disable_all_buffers(). So we also need to free the active scan mask here, otherwise it will be leaked. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
