Subject: [PATCH v10 3/8] iio: buffer-dmaengine: use %zu specifier for sprintf(align)
Date: Mon, 16 Mar 2020 17:50:30 +0200	[thread overview]
Message-ID: <20200316155035.25500-4-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20200316155035.25500-1-alexandru.ardelean@analog.com>

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")
Reported-by: kbuild test robot <lkp@intel.com>
