iio: kfifo: Remove unused argument in iio_kfifo_allocate
indio_dev was unused in function body plus some small style fix - add new lines after "if(sth) return sth" and before the last return statement. The argument was removed also in its client. Signed-off-by: Karol Wrona <k.wrona@samsung.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
