Subject: arm: Fix uninitialised warning with gcc 4.8
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bef2086f5bb1ef350181791c6dff14d0964a5680;p=gem5.git

arm: Fix uninitialised warning with gcc 4.8

Small fix for a warning that prevents compilation with gcc 4.8.1 due
to detecting that a variable might be uninitialised. The fix is to
assign a safe default.
