Subject: [PATCH 08/17] staging:iio:adc:ad7280a: Drop unused timestamp channel.
Date: Mon, 14 Jun 2021 12:34:58 +0100 [thread overview]
Message-ID: <20210614113507.897732-9-jic23@kernel.org> (raw)
In-Reply-To: <20210614113507.897732-1-jic23@kernel.org>
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.
