Subject: bus: del unnecessary init var
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8adc8e1657e19849c02c764e371478a05ca83c57;p=thirdparty%2Flinux.git

bus: del unnecessary init var

The compiler generates initialization instructions,
which consume additional CPU cycles. the
sysc_clockdomain_init should assign a value
to 'error' before it is read.so the var don't need init
to 0.
