4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Williams <dan.j.williams@xxxxxxxxx>
commit af7d9f0c57941b465043681cb5c3410f7f3f1a41 upstream.
Fix the format specifier so that the attribute can be parsed correctly.
Currently it returns decimal 1000 for a 4096-byte alignment.
Reported-by: Dave Jiang <dave.jiang@xxxxxxxxx>
Fixes: 315c562536c4 ("libnvdimm, pfn: add 'align' attribute, default to HPAGE_SIZE")
