From: Jonathan Cameron <Jonathan.Cameron@huawei.com> The driver doesn't support buffered mode, so a timestamp channel that is entirely hidden from userspace without buffer mode is rather pointless. Drop it. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> --- drivers/staging/iio/adc/ad7280a.c | 14 +------------- 1 file changed, 1 insertion(+), 13 deletions(-)
