libnvdimm, pfn: fix align attribute
Fix the format specifier so that the attribute can be parsed correctly. Currently it returns decimal 1000 for a 4096-byte alignment. Cc: <stable@vger.kernel.org> Reported-by: Dave Jiang <dave.jiang@intel.com> Fixes: 315c562536c4 ("libnvdimm, pfn: add 'align' attribute, default to HPAGE_SIZE") Signed-off-by: Dan Williams <dan.j.williams@intel.com>
