Subject: [1975] Use reference instead of pointer
X-Git-Tag: trac2351_base~97^2~9^2~4^2~5^2~13
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=abf827ef79067d74865bc4e6da349788e71fca7d;p=thirdparty%2Fkea.git

[1975] Use reference instead of pointer

As the pointer should never be NULL anyway, it might be better to pass
reference.
