Subject: nvdimm: use the right length of "pmem"
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2d9a02744f5a2e8325fc0c3e5533593261cead0a;p=linux-beck.git

nvdimm: use the right length of "pmem"

In order to test that the name of a resource begins with "pmem", call
strncmp() with 4 as length instead of 3 to match the whole prefix.
