Subject: xzless: Rename unused variables to silence static analysers.
X-Git-Tag: v5.3.2alpha~163
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=f76f7516d6a1c832f61810c82e92d151cc80966c;p=thirdparty%2Fxz.git

xzless: Rename unused variables to silence static analysers.

In this particular case I don't see this affecting readability
of the code.

Thanks to Pavel Raiskup.
