Subject: [PATCH v12 3/8] iio: buffer-dmaengine: use %zu specifier for sprintf(align)
Date: Sun, 22 Mar 2020 19:53:20 +0200 [thread overview]
Message-ID: <20200322175325.42469-4-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20200322175325.42469-1-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>
