Subject: mm/damon: remove unused target param of get_scheme_score()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c9cb94c6b85a2854ae03c874331b0880ee735441;p=thirdparty%2Fkernel%2Fstable.git

mm/damon: remove unused target param of get_scheme_score()

damon_target is not used by get_scheme_score operations, nor with virtual
neither with physical addresses.
