Subject: [PATCH RESEND 5/8] iio: magn: rm3100: Fix alignment of buffer in iio_push_to_buffers_with_timestamp()
Date: Sun, 13 Jun 2021 16:22:58 +0100 [thread overview]
Message-ID: <20210613152301.571002-6-jic23@kernel.org> (raw)
In-Reply-To: <20210613152301.571002-1-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 an explicit structure is not used, because this buffer is used in
a non-trivial way for data repacking.
Fixes: 121354b2eceb ("iio: magnetometer: Add driver support for PNI RM3100")
