    Subject[PATCH 4.9 106/116] libnvdimm, pfn: fix align attribute
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Dan Williams <dan.j.williams@intel.com>

    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@intel.com>
    Fixes: 315c562536c4 ("libnvdimm, pfn: add 'align' attribute, default to HPAGE_SIZE")
