Subject: target-mips: Remove assignment to a variable which is never used
X-Git-Tag: qemu-xen-4.4.0-rc1~6^2~127^2~2^2
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=6c86f405efd6532b58ad1b607cc9f11e856ef5ca;p=qemu-upstream-4.4-testing.git

target-mips: Remove assignment to a variable which is never used

This assignment causes a compiler warning for compilations with the compiler
option -Wunused-but-set-variable (which is included with -Wextra).

Removing it allows using -Wextra for QEMU code without suppressing too many
extra warnings.
