    Subject[PATCH AUTOSEL 5.7 128/388] iio: buffer-dmaengine: use %zu specifier for sprintf(align)
    Date
    From: Alexandru Ardelean <alexandru.ardelean@analog.com>

    [ 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")
