Lars Möllendorf 2d44f11a4c iio: buffer: align the size of scan bytes to size of the largest element
commit 883f616530 upstream.

Previous versions of `iio_compute_scan_bytes` only aligned each element
to its own length (i.e. its own natural alignment). Because multiple
consecutive sets of scan elements are buffered this does not work in
case the computed scan bytes do not align with the natural alignment of
the first scan element in the set.

This commit fixes this by aligning the scan bytes to the natural
alignment of the largest scan element in the set.

Fixes: 959d2952d1 ("staging:iio: make iio_sw_buffer_preenable much more general.")
