Subject: libnvdimm, pfn: fix restoring memmap location
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=45eb570a0db3391c88cba04510a20fe7e4125497;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

libnvdimm, pfn: fix restoring memmap location

This path was missed when turning on the memmap in pmem support.  Permit
'pmem' as a valid location for the map.
