X-Git-Tag: v4.7-rc1~78^2~4^2~7
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=947df02d255a6a81a3832e831c5ca02078cfd529;p=linux.git

libnvdimm, pmem: clean up resource print / request

The leading '0x' in front of %pa is redundant, also we can just use %pR
to simplify the print statement.  The request parameters can be directly
taken from the resource as well.
