[ Upstream commit 6eb3b8acfd079104571c207d4524743b6acc6550 ]
The 'size_t' type behaves differently on 64-bit architectures, and causes
compiler a warning of the sort "format '%u' expects argument of type
'unsigned int', but argument 3 has type 'size_t {aka long unsigned int}'".
This change adds the correct specifier for the 'align' field.
Fixes: 4538c18568099 ("iio: buffer-dmaengine: Report buffer length
requirements")
