Subject: [PATCH 07/11] iio: potentiostat: lmp91000: Fix alignment of buffer in iio_push_to_buffers_with_timestamp()
Date: Sat,  1 May 2021 18:13:48 +0100	[thread overview]
Message-ID: <20210501171352.512953-8-jic23@kernel.org> (raw)
In-Reply-To: <20210501171352.512953-1-jic23@kernel.org>

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Add __aligned(8) to ensure the buffer passed to
iio_push_to_buffers_with_timestamp() is suitable for the naturally
aligned timestamp that will be inserted.

Here structure is not used, because this buffer is also used
elsewhere in the driver.

Fixes: 67e17300dc1d ("iio: potentiostat: add LMP91000 support")
