Subject: [PATCH -next] nvdimm: btt.c: fix format string warnings

From: Randy Dunlap <rdunlap@...radead.org>

Fix format warnings (seen on i386) in nvdimm/btt.c:

../drivers/nvdimm/btt.c: In function ‘btt_map_init’:
../drivers/nvdimm/btt.c:430:3: warning: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘size_t’ [-Wformat=]
   dev_WARN_ONCE(to_dev(arena), size < 512,
   ^
../drivers/nvdimm/btt.c: In function ‘btt_log_init’:
../drivers/nvdimm/btt.c:474:3: warning: format ‘%lx’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘size_t’ [-Wformat=]
   dev_WARN_ONCE(to_dev(arena), size < 512,
   ^
