Subject: intel: Avoid 'may be used before initialised' warning.
X-Git-Tag: mdadm-3.0-devel2~50
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d9b420a5cdd6c10ee42dfeea3026740fa787b050;p=thirdparty%2Fmdadm.git

intel: Avoid 'may be used before initialised' warning.

When compile with -Os, the compile doesn't work out that the
variable is always initialised before usage, so we tell it.
