Subject: [PATCH 06/11] iio: cros_ec_sensors: Fix alignment of buffer in iio_push_to_buffers_with_timestamp()
Date: Sat,  1 May 2021 18:13:47 +0100	[thread overview]
Message-ID: <20210501171352.512953-7-jic23@kernel.org> (raw)
In-Reply-To: <20210501171352.512953-1-jic23@kernel.org>

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

The samples buffer is passed to iio_push_to_buffers_with_timestamp()
which requires a buffer aligned to 8 bytes as it is assumed that
the timestamp will be naturally aligned if present.

Fixes tag is inaccurate but prior to that likely manual backporting needed.

Fixes: 5a0b8cb46624c ("iio: cros_ec: Move cros_ec_sensors_core.h in /include")
