[PATCH 4.9 106/116] libnvdimm, pfn: fix align attribute

From: Greg Kroah-Hartman
Date: Fri Jan 06 2017 - 17:28:15 EST


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.
