Subject: [PATCH 2/3] iio: core: simplify alloc alignment code
Date: Fri, 8 May 2020 17:13:05 +0300	[thread overview]
Message-ID: <20200508141306.17222-2-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20200508141306.17222-1-alexandru.ardelean@analog.com>

There was a recent discussion about this code:
  https://lore.kernel.org/linux-iio/20200322165317.0b1f0674@archlinux/

This looks like a good time to rework this, since any issues about it
should pop-up under testing, because the iio_dev is having a bit of an
overhaul and stuff being moved to iio_dev_priv.
