[ Upstream commit 149d17140bcedc906082c4f874dec98b1ffc5a90 ]
Kernel test robot detected name collision when compiled on 'um' architecture. Rename "to_phys()" to "pmem_to_phys()".
drivers/nvdimm/pmem.c:48:20: error: conflicting types for 'to_phys'; have 'phys_addr_t(struct pmem_device *, phys_addr_t)' {aka 'long long unsigned int(struct pmem_device *, long long unsigned int)'}
