Subject: [PATCH 0/2] IIO: Alignment fixes part 1 - sizes too small as well.
Date: Sat,  1 May 2021 17:53:12 +0100	[thread overview]
Message-ID: <20210501165314.511954-1-jic23@kernel.org> (raw)

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

I finally got around to do a manual audit of all the calls to
iio_push_to_buffers_with_timestamp() which has the somewhat odd requirements
of:
1. 8 byte alignment of the provided buffer.
2. space for an 8 byte naturally aligned timestamp to be inserted at the
   end.

As discussed previous in
https://lore.kernel.org/linux-iio/20200920112742.170751-1-jic23@kernel.org/
it is not easy to fix the alignment issue without requiring a bounce buffer
(see part 4 of the alignment fixes for a proposal for that where it is
absolutely necessary).

In these cases the buffer is neither big enough, nor correctly aligned
so fix both issues in one go.
